I have used Bdos calls from Turbo in CPM86 to get the date and time. No assembly language is needed. In MS-DOS the procedure should be similar. Set up the registers like it says in the Turbo manual (you have to declare a record for it). For date do an interrupt 21h (there is a Turbo function to do interrupts but I don't have the manual here so I am not sure what it is called - probably Intr) with AH (thats the high byte of AX) = 2Ah. For For time AH = 2Ch. Date is returned as CX = year, DH = month, DL - day. Time is returned as CH = hours, CL = minutes, DH = seconds, DL = 1/100 seconds. This should all work the first time, however I have found more than a few typos in the Assembly book I am using so I can't guarantee it.

To avoid snow on some cards (like IBM's), you have to put in some code to test the retrace status..if the card is retracing (and the signal therefore blanked), you can update the screen memory. If not, and you update screen memory anyway, you'll get snow because of conflicting access to video RAM. Newer designs (such as on the ZDS Z-15x and 2xx machines) do this checking in the video interrupt handler code or in the hardware of the card itself. If you check retraces on the newer style card, you'll unnecessarily slow down screen displays (but be guaranteed of no snow!). I realize that adding 'nonstandard' sequences is a nasty thing to do in a standard environment, but this is one case I feel the user should be given the option.

Weiss Subject: DOS Console Handling Query To: info-ibmpc@USC-ISIB.ARPA I have uploaded NANSI from the program library and it raises some questions about DOS console buffering that I hope some DOS maven can answer. I noticed that when raw mode is turned on there is no processing of escape sequences or tabs if I used the DOS write function call to STDOUT. My question is how do device drivers, buffering, int 29h, raw mode and BIOS teletype interface all work together? In light of this, what is the difference between using DOS function calls 3f and 40 to do console I/O and using the console-specific calls. ------------------------------ Date: Tuesday, 25 February 1986 13:26:19 EST From: Paul.Birkel@k.cs.cmu.edu To: info-ibmpc@usc-isib.arpa Subject: Query: Exchanging files with an NBI Machine Here's an interesting problem. I need to exchange files with an NBI Word Processing "machine". Don't ask me why anyone would actually buy one of these beasts instead of a CHEAPER (!) PC-AT or CP/M machine, but here's the situation. They have one or two 5 1/4 inch floppies, no hard disk, are probably 8 bit machines, and drive a multiple port letter-quality printer. We've been told that to connect another brand machine to one of the "extra" LQP ports will void the warrenty. Heaven forbid! The better solution would be able to read/write to NBI disks, if possible. Since there are the appropriate software packages to transfer between CP/M formats and PC-DOS formats, it would be nice to do the same with the NBI format. And seemingly reasonable, too. Although our current machine is a CP/M, we have access to a PC-AT as a potential intermediary. The question is, how to get from one of them to the NBI? Assuming that files are ASCII (am I assuming too much?), and that a standard floppy controller chip is used, this should be possible. Unfortunately, NBI has been very unhelpful (as you can gather from the above comment). I guess they just want to sell more of their machines rather than to talk with the rest of the world. Can anyone help me with additional information, technical data, a word of advice, solace? Also, if you know of any other forums than info-cpm and info-ibmpc in which such a question could be addressed would you please direct this message there?

My first comment is that they do not talk very well to anything! There is a Canadian company (the name escapes me at the moment) that manufactures a box that hooks-up to your PC/AT. This box has, if I remember right, one 8" drive & one 5 1/4 drive. You put their conversion floppy into the AT and your source/destination floppies in and the conversion box attempts to translate from one wp disk to the other. It will also do a wp to ascii conversion. The big problem is that this box & software supposedly costs BIG $$$ ($7k+). For the money, though, it is supposed to work well. If you want to go that route, get back to me and I'll try to dig-up some details. The "cheap" way to go is to connect a pc to the NBI's serial port and "transmit" or "receive" documents from/to the NBI. We have found the fastest speed that really works is 4800 bps. Generally, the screen shows a loss of characters, but the characters really do show up. If you transfer a document from the NBI, anything that is underscored gets transferred as just the underscores. (It looks like NBI handles underscoring by typing the word, backspacing and underlining.) Our search for a file transfer protocol for the NBI was unsuccessful. BTW, the VT100 emulator for the NBI doesn't work if you try to use it going into a UNIX host and want to do vi. NBI's response was "Yes, we know of that problem; no, we're not going to fix it; and you should realize that our VT100 emulator doesn't do anything really sophisticated like true cursor addressing." One more thing. NBI makes a board for the PC that allows you to do NBI word processing on an IBM PC. Perhaps that will allow you to read NBI disks on the PC. Since I don't have one of those boards, I can't really tell you much. Maybe NBI can (ha!)

The woman at Microsoft who explained the problem to me said that DOS interupt 14h which is used by the basic compiler to facilitate the opening of communications, does a continuous check for ctrl break. If ctrl break is encountered, then the program attempts to halt (!) processing. She also referred me to the book PROGRAMMING THE IBMPC by NORTON (which I don't have unfortunately). MY QUESTION IS... Does anybody out there know if the following is the easiest way to prevent from getting through and crashing my program? 1) open com1 .... 2) execute a com off command 3) whenever input output is desired, check for a character from the remote user at the com port using the inp function.... 4) if a character is sent and if it is ctrl break, then disallow it else pass the character along to an input buffer in the program..... From: SYSOP Date: 23-Feb-1986 12:31:03 From the description of the bug by Bill Angus, I would recommend that you write an Assembler procedure for Quick-Basic which grabs the contents of INT 14h (ie saves the four bytes at 0:50h and loads its entry there) and then proceeds to clear the error bits out of the COM1 status at port 3FDh, before passing control onto the BIOS com INT 14h handler, by PUSHing the four bytes (saved from 0:50h) on the stack, then IRET. This will guarantee that the BIOS never sees a communications error! ------------------------------ Date: 23 February 1986, 14:36:02 EST From: Peter Allsop (Chemical Eng., UofW) To: info-ibmpc@usc-isib.ARPA Subject: Experience with QNX Operating System This is in response to a recent query by Tom Helbekkmo concerning the QNX operating system. I have been using QNX on an IBM-PC (576K RAM, 5M Davong, 1 floppy) for 4 or 5 years (I started with a pre-release version), and on a DEC Rainbow for about 2 years (off and on). The majority of my work involves real time process control, were speed and efficiency at run time are more important than ease of software development. I am not a Unix expert, nor any other kind for that matter, and cannot comment on how Unix-like QNX is (Quantum claims 4.something compatibility). Neither do I have any experience with the networked version of QNX, although I have a few friends who use (and like) it. Weigh my comments accordingly. >>> The Operating System: Basically I am very satisfied with the operating system, now that I know how to use it. The user is given a great deal of control over the environment, and the device interface proceedures are very easy to use (eg: much better than Venix on the Pro-350). A number of useful (to me) utilities are included, such as: -Device independant graphics utilities, which allow you to define your own devices after writing (and compiling) the program. -User tasks can "adopt" devices, effectively replacing the device administrator for that device. -Define your own memory resident shared libraries. -Intertask signalling and message handling proceedures. -The basic utilities to allow the user to manage resources independantly of the OS (semiphores, etc). -An auto-answer modem control program, so you can sign on from home. -Drivers for several different hard disks, and a RAM disk utility. -A windows handling routine, allowing up to 4 windows on the console. -A full screen editor that makes XEDIT on VM/CMS (KEDIT on IBM-PC) look sick, both in speed and power. -A whole bunch of other stuff that I rarely (never) use. These allow system accounting, debugging, and ??. The C compiler is very standard, and comes in two flavors: shared library math (SLM) and inline 8087 math (IM). The SLM uses one of two memory resident shared libraries (both supplied), one using the 8087 and the other ignoring it. The advantage of this version is that you can move programs between computers without having to worry about an 8087, but it is *slow*. The IM version generates (you guessed it) inline 8087 code, and is about 10 fold faster than the shared lib 8087 version. I think that Quantum is going to merge the two compilers, the user supplying a compiler flag to select SLM or IM. The code generated by the IM C compiler (the one I use) is very efficient. I rarely get even a 2 fold speed increase when I re-code in assembler, and most of my software involves a lots of iteration! In fact I don't even bother using assembler any more, unless it is a very heavily used math routine. There are several other QNX compilers available, including BASIC, Pascal, and Fortran (I think). Quantum claims that you can mix (link) program segments coded in different languages together, but I've only used C. There are also several "extras" available, including a word processor, a spellin checker, a database manager, and a utility which allows a DOS program to run under QNX. QNX does have a few drawbacks. My major complaint is that the manuals don't have an index!! This isn't a great hassle once you get to know them, but in the interm ... it's hell! Another annoyance is the size of the system itself, you only get about 40K of user space out of a 256K machine! Finally, the C compiler (at least) will only allow 64K of code and 64K of data. This doesn't bother me, since I can always request a chunk of memory from the OS and manage it myself (utilities are provided), but if you don't want to ... >>> The Company (Quantum): This is were QNX falls down the most. Quantum is a technically oriented company, and they aren't too swift at marketing. This means that they tend to be a bit slow on delivery, and don't understand user's complaints about the manuals (see above). Their technical support, however, is excellent. Quantum includes two types of support with every system: a telephone hotline and an on-line update service. The hotline puts you in touch with a systems programmer, who has access to a duplicate of your OS. (Quantum maintains an on- line database which tells them which version of each module you have). I find these people very helpful, and their turn around on OS fixes is rarely greater than 24 hr. Even better, though, is the on-line update system. The on-line update system allows you to phone Quantum and sign-on to their database system. This system maintains bug reports, explanatory notes (eg: recovering erased files), current versions of the OS and utilities, and a mail system. Using this you can download system updates directly over the phone, or submit questions/bug reports with examples. They are even talking about connecting this to DATAPAC (thus TYMENET, ...). The update service is so good, in fact, that I can almost forgive them their manual!

Bob Knight ------------------------------ From: cramer%kontron.UUCP@BRL.ARPA Subject: Compiling Really Large Programs With Microsoft C V3.0 Date: Thu, 20-Feb-86 11:25:33 PST This is a helpful hint to those of you building really big programs on the IBM using Microsoft C V3.0. We have a large piece of C that we are developing simultaneously on a VAX and IBM AT -- roughly 40,000 lines of C, all linked together, no overlays. Unlike a lot of commercial products, our program has very large quantities of static data. (Your average spreadsheet has know problem gobbling up to and beyond 640K, but most of the memory is allocated -- not static.) If you don't read the Microsoft C manual in excruciating detail, you would think that compiling in large model (/AL on the command line) would be adequate for the largest program that will fit into the address space. Not so! From section 8.1.1.2 of the Microsoft C Compiler User's Guide: All segments with the same group name must fit into a single physical segment, which is up to 64K bytes long. This allows all segments in a group to be accessed through the same segment register. The Microsoft C compiler defines one group named DGROUP. The NULL, _DATA, CONST, BSS, c_common, and STACK segments are grouped together in the data group, called DGROUP. This allows the compiler to generate code for accessing data in each of these segments without constantly loading the segment values or using many segment overrides on instructions. DGROUP is addressed using the DS or SS segment register. DS and SS always contain the same value except when the "u" or "w" option of the /A option is used. As you can see by table 8.1 that follows in the same manual, even a large model program will try to put all the global and static data into one group, and that one group will be entirely in a 64K segment. The symptom is "fixup overflow near
in segment in .OBJ() offset " messages from the linker. The section quoted above might tempt you to use an option like /Alfu to allocate different segments for the stack and the data segments. In fact, this is what I tried first, and for reasons that are not immediately obvious, our program stopped dead in its track, looping endlessly. What does work is to use the options /AL and /Gt. From section 7.12 of the User's Guide: /Gt [] By default, the compiler allocates all static and global data items to the default data segment. The /Gt option causes all data items greater than bytes to be allocated to a new data segment. The effect is to create separate segments AND GROUPS for each module's static and global data. This doubtless requires more setting of segment registers -- but I can't see any obvious slowing of our program after recompiling with the /Gt option. One other item: a very large program will quickly exceed 128 segments, which is the default number of segments the Microsoft Linker likes to work with. Use the /SEGMENTS: option on the link to deal with this. ------------------------------ Date: 24 Feb 1986 13:31:48-EST From: mlsmith@NADC To: Ghenis.pasa@Xerox.COM, info-IBMPC@USC-ISIB Subject: Color & Mono Cards in AT I have had both an IBM Monochrome and Color Graphics Adapter plugged in for about four months on an AT. I do not use either of the programs you mentioned. Despite appearances of simultaneous operation, the AT only talks to one display at a time.I use the monochrome display as a menu tablet, and then go to the color monitor for my programs. This leaves the menu up. More elaborate schemes are certainly possible. Two Adapters of the same type _is_ a problem, but I'm not sure about the EGA.

I had been working with a large model Lattice C program, and tried to use an invalid pointer. Since DOS has no memory protection, it is possible to write over DOS, and whenever I do this, it always seems to be the disk driver database I hit. The disk failed badly after one particular execution of a program with a bad pointer, and I deduced that I had written over the driver in such a way that instead of writing a data block into a file, it wrote it in a random, and particularly wrong, block on the disk. The symptom was a lot of trashed files, and CHKDSK barfed badly. Various raw disk manipulation tools hung or refused to run. I ran the Advanced Diagnostics, Conditional Format, and it started from track 305, rather than the expected 610. When the diagnostics completed, it complained that there was less than 10 MB useable on the hard disk. The theory was that there was a place on the disk that told the world, even Adv Diags, about the disk, and that Formatting did not touch that area. Setup correctly identified the disk as Type 2, and the interleave was correctly set to 3, yet I had only a 10 MB disk. I tried to delete and restore the DOS partition, but after the DOS format, DOS thought it was a 10MB disk. It worked, but missing half the capacity. That theory seems to have been proven correct. I was able to restore my hard disk to relative normalcy by using the "Change Interleave Factor" function on the "Format Menu" of the hard disk diagnostics. The interleave factor is normally set to 3; I instructed the program to "change" it to 3. My guess was that it might, as a side effect, reinitialize other disk characteristics in the correct way. It worked! The Advanced Diagnostics Conditional Format now counts down from track 610, which means I again have a 20 Mb disk. Interesting that at least some of the problems I formerly attributed to bad hard disks on the AT were in fact software problems that resulted of the missing memory protection in DOS.

I did finaly get ahold of the LOTUS Tech rep and they were not the most reassuring of supporters.

This done they still didn't seem real positive of the results as the informed me that if that didn't work to delete the serial driver. All said and done it didn't have any new results in any form!

For example FOO PROC NEAR 10$: JCXZ 20$ LOOP 10$ 20$: FOO ENDP BAR PROC NEAR 10$: LOOP 10$ BAR ENDP would be legal, and not result in "Redefinition of Symbol" errors. ------------------------------ Date: Sun, 23 Feb 86 09:09:40 PST From: Lawrence_Anthony_Smith%UBC.MAILNET@MIT-MULTICS.ARPA Subject: Problem with 27 Lines on the EGA I am having difficulty in displaying 27 lines of character data instead of the normal 25 lines. I am using a PC/AT with the Enhanced Graphics Adaptor (EGA). I'm writing the program in Microsoft Assembler V3.0. Does anyone have any useful ideas about how to go about this task?

Unfortunately, disk space is allocated in 8K blocks leading to a great deal of wasted space. I would appreciate hearing from anyone who can explain what I can do to reduce the allocation size (and who doesn't mind explaining it). Please reply to EB%MIT-OZ@MIT-MC; thanks. ------------------------------ Date: 24 Feb 1986 04:57-PST Subject: Prolog Query From: BSCHAAR@USC-ISIF.ARPA To: info-ibmpc@USC-ISIB.ARPA A friend of mine needs a pointer to the developer's name, address, and phone number of Prolog.

The board is silk-screened with IC identification, but came without a circuit diagram. The only identification is 'MBE-XT'. Any help in tracking down the manufacturer or a circuit diagram would be greatly appreciated.

Clearly, this information must be kept within dos, and is accessible through some venues, for ansi.sys and various other packages are able to modify it. However, I have not seen any hooks for retrieving the information. - John Pezaris (pz@mit-vax) ------------------------------ Date: Tue, 25 Feb 86 16:08:34 EST From: Andy Adler Subject: Problem with MS-DOS command line length To: Info-IBMPC@usc-isib.arpa I am having problems with the MS-DOS limitation on command line length. The version of the MS C compiler that comes in the Windows Toolkit combines p0.exe and p1.exe into one new p1.exe. Thus the command line for the new p1.exe gets long since it receives switches for "two programs". If I want to keep my include files in more than one directory the multiple -I switches will overflow the command line. I can work around the problem by keeping all my includes in one directory with a relatively short path. However, this is not the REAL solution. Is there any way to lengthen the command line length limit? Has anyone come up with a better work around for this problem? Thanks, Andy Adler BBN Communcations. ------------------------------ Date: 25 Feb 86 11:27:56 PST (Tuesday) Subject: Intel 80186 Assembler Query From: Kadifa.osbunorth@Xerox.COM To: INFO-IBMPC@USC-ISIB.Arpa I need some pointers for an Intel 80186 compatible assembler, linker, locater written in C.

We are also looking at a printer that only hangs off of PCnet (the new IBM pageprinter). Does anyone know if there is a good way to nail PCnet and EtherShare together? Current plan is that the VAX is our 3Com server - we won't have a PC based server in the EtherShare net. If we have to - we will put in a PC based 3Com server and run the pageprinter off of it.
