He thought that it is maybe his A-1000, so we tested it with > my AMIGA-2000 (A-2000B Rev4.3, European/PAL-Model, A2058, A2090-ST1096N). First of all, use AmigaDOS 1.3. There were improvements to the serial.device. Also, just for completeness, you might want to use AmigaDOS 1.3.2 since it's always nice to be running with the latest bug-fixes. You did a pretty good analysis, but you had one big flaw: You used 2 slow terminal programs. JRcomm is good, but not at high speeds. Platinum Online is a silly little program that is not well respected. Try VT100 2.9A (free) or ATalk-III+ (commercial). You asked "why do term program permit high baud-rates when they can't handle them?" Well, it's because most aren't tested at high baud rates. Commercial software does get good testing and you'll only see the baud rates listed that they can actually do. (Oops, I should say "*good* commercial software gets good testing). If you notice, VT100 2.9A only lists the tested baud rates. The next version will include 19.2Kbps because I've tested it at that rate. So, obviously the question is, "where is the problem?". Well, basically the serial.device in pre-1.3 AmigaDOS wasn't so hot, and 1.3 only has a couple improvements. Commodore has stated that there will be a new serial.device someday (presumably in 1.4) that will have been re-written from scratch and will be quite fast. Obviously the Amiga can handle it. It just takes good software. (I say that because the ASDG serial board doesn't have its own CPU and they get great results. Results so good that ASDG posted that it seems futile to produce a board with a CPU now that they've seen what a well-matched hardware/software design can do on the Amiga). [I'm not speaking for ASDG, I'm just a happy customer.] So, basically the solution is to get better software: (1) get a new application and (2) get 1.4. Sadly, you can only do #1 right now. -- tlimonce@drew.edu Tom Limoncelli As seen in USA Today & tlimonce@drew.uucp +1 201 408 5389 Rec.Humor.Funny! tlimonce@drew.Bitnet Stock quote: Commodore stock closed limonce@pilot.njin.net at $7.25 (-.25) on 4-11-1990.
