Both these did not work. (Effect: legitimate data was being received by the asynch port but the service subroutine was not being run). As checks, I used the same subroutine residing in the same place in mem to run under a software interrupt. This worked perfectly. Another check was to use the identical configuration with a program that used a scan loop to verify the reception of a byte at the asynch port. This method was entirely success- ful. > I just finished writing interrupt driven async routines for an operating system project (Xinu). Here is a brief summary of how to get async interrupts working. Hardware Location of Device Interrupt Interrupt line interrupt vector ------ ---------- -------------- -------------------- COM1 0Ch IRQ4 0000:0030 COM2 0Bh IRQ3 0000:002C There are several things that must be done for async interrupts to work. 1. You should get the current interrupt vector for the com port(s) and save it. Then replace the current vector with the vector (address) of your routine. If a software interrupt works then the vectors were changed properly. 2. The interrupts must be enabled in the 8250. There are 4 types of interrupts that can be enabled or disabled for the 8250: receiver line status (error), received data available, transmitter holding register empty, and modem status (change). The interrupts are enabled by setting the appropriate bits in the interrupt enable register (base address+2) of the 8250 to 1. To start with, all that is needed is to enable the received data interrupt. Enable the trans. holding register empty interrupt when you send data and disable it when you have nothing else at the monent to send. Later add the receiver line status and modem status routines and enable those intr. 3. The interrupt line must be enabled in the 8259 interrupt controller. The 8 hardware interrupt lines (IRQ0-IRQ7) go into the interrupt controller. The controller has an 8-bit interrupt mask to enable or disable each interrupt. Setting the appropriate bit to 1 disables that interrupt, clearing the bit enables that interrupt. On the PC, the interrupt mask is at I/O address 21H. 4. The 8250 interrupt must be enabled on the asynchronous communications adapter. This is the the step that took me a bit to figure out. On the IBM async card, the 8250 interrupt output is gated to the IRQx line. Two other 8250 outputs, OUT1 and OUT2, enable the gate. To enable the interrupt line, you have to set OUT1 and OUT2 to 1. This is not a requirement of the 8250, but of the IBM async card. I don't know if this applies for other async cards. Check the schematics if you have them available. There is also a hardware jumper that should have be set when the async card is installed in the machine. So how can you do you acompilsh all of this? Here is a short, simplified example written in C. #define COM1_ADDR 0x3f8 address of COM1: #define COM1_INT 0x0c interrupt number of COM1 #define COM_IER 2 offset of Interrupt Enable Register #define COM_MCR 4 offset of Modem Control Register #define COM_OMSK 0x0c mask to set OUT1 and OUT2 bits in 8250 #define IRQ4_MASK 0xef mask to enable IRQ4 in 8259 struct vector { int ip; /* hold old interrupt vector ip */ int cs; /* hold old interrupt vector CS */ } save_vector ; int intr_routine(); routine to be called when intr. occurs /* set the base address of the com port */ ioaddr = COM1_ADDR; /* set the interrupt number */ intvec = COM1_INT; /* get and save current interrupt vector */ getvec ( intvec, &save_vector ); /* install new interrupt vector */ setvec ( intvec, intr_routine ); /* enable all interrupts in 8250 */ outbyte (ioaddr+COM_IER, 0x0f); /* get current mask from interrupt controller */ tmp = inbyte (0x21); /* clear (enable) IRQ4 */ tmp = tmp & IRQ4_MASK; /* write new mask to interrupt controller */ outbyte (0x21, tmp); /* get current modem control register from 8250 */ tmp = inbyte (ioaddr+COM_MCR); /* set OUT1 and OUT2 bits */ tmp = tmp & COM_OMSK; /* write modem control register back to 8250 */ outbyte (ioaddr+COM_MCR, tmp); I hope this helps. There is more that could be said about this but this is already longer than I had intended. Let me know if you have any more questions. Andrew J.

Both these did not work... The first things that came to my mind regarding your problem were that maybe you were not initializing the port correctly (baud, parity, etc), enabling interrupts when you were done servicing an interrupt, etc. I've done some work writing serial interrupt handlers for MS-DOS, and recently implemented one for a project I am working on. I based my interrupt handler and initialization on the Kermit MS-DOS sources. Below is a bit of the code in MASM that sets up the interrupt handler, and the interrupt handler itself. You might want to take a look at the Kermit sources which are available from Columbia University. (The file MSXIBM.ASM has the serial int handler code.) Good luck.

This is also a 6/8 mHz model. The speedup is controlled from the keyboard (ctrl-alt-\) and works on the fly. The setup menu like to one you get on a real AT by booting diag is available at all times via (ctrl-alt-enter) so you can change the clock easily. I have tested the machine with an EGA and monochrome together and it works fine. The construction seems much better than any other clone that I've seen and is not far from the quality of a real IBM machine. The front panel LEDs are also in securely and can be set to indicate clock speed or power. I get the impression from the documentation that the machine was recently improved so I guess that I was lucky. Also, when I ordered it they said that I should expect delivery in 3 weeks. Tonight at dinner I got a fortune cookie which read "Something nice is coming to you in the mail." and by God there it was 3 weeks after the order at my door. I think the machine is blessed.

However, I am willing to speculate on one method. I have a program called "devices" (I apologize for never sending it in to the library). The program scans the list of device drivers and prints the device headers. The problem is, how do you find the beginning of the device driver chain? I don't know of a documented method to get it. Here's my undocumented method. Open an FCB for NUL. In the "Reserved for system use" area (please, no hate mail from Microsoft!) there is a field which points to the device header of the device just opened. NUL just happens to be at the head of the list (as far as I know). The dangers of this method are: 1) The existance of this field is undocumented, 2) its location depends on which version of DOS you are running, 3) there's no guarantee that NUL will continue to be the head of the list (maybe it isn't really so in the first place), and 4) you won't make any friends at Microsoft if you use this information. For your application, dynamically loaded device drivers, you might just patch the new driver into the list somewhere. I cannot assure success: DOS may have a location containing the total number of block devices, and that might need to be patched, too. The rest of your driver would be the usual exit-and-stay-resident stuff. Happy hacking. Craig Milo Rogers ------------------------------ Date: Sat, 30 Aug 86 15:17:55 edt From: Mike Ciaraldi To: info-ibmpc@usc-isib.arpa Subject: FCOMP.C Use I recently grabbed FCOMP.C from the info-ibmpc archives at usc-isib, and ran into a few very minor problems. After finding solutions, I thought I should let other potential users know. 1) In order to compile this program with Microsoft C (version 3), you must add this line to the source code: #include to allow the compiler to find the "isdigit" function. This is not needed if you use Lattice C (version 2.14). 2) Again when using Microsoft C, you must increase the stack size to avoid gettng the "stack overflow" error as soon as you try to run FCOMP. An easy way to do this is, after linking, to give the command: EXEMOD FCOMP.EXE /STACK 6000 You can also increase the stack size while linking, and avoid this extra command. I also got "stack overflow" when using Lattice C, and was never able to find a stack size big enough to let it run. 3) If you use the default memory model in Microsoft C, the program will be limited to 64K maximum data. This means you can only compare files up to about 16K bytes in length each, since both files and some scratch space are held in memory. Adding the "/AL" switch to your compile command will give you the large memory model, which allows memory access up to the total amlount in the machine. However, any one data structure is limited to 64K bytes. So, you are now limited to files of 64K length each. If you use the large model, you will have to move the stack size up to 8000, instead of 6000. 4) You may want to increase the constant "MAXLINES" to increase the number of lines of text allowed per file. I moved it up to 3000 with no problems. Maybe some of this information can be included with the documnentation for this program in the archives.
