My suspicion, though, is that BOOT is checking which version of DOS it's running under and doesn't expect to find a version 3. If this is the case, it should be a simple matter to come up with a fix that would use DEBUG to change a JNE (probably) instruction to a JB one. This would likely be found early on in the program. But, note, I'd only try this i) after reading the docs thoroughly to make sure there was no other problem and ii) after trying to contact the original author to verify the problem. > Last year, I think you wrote about terminal emulation programs >on the RB.

Kermit v2.29 (4 Jul 86) supports 19200 baud and I've heard on some AT's such baud rates are also supported. Should you try Kermit, get rid of all TSR's on both machines and use 1 character checksums plus anything else you can think of to make the transfers go faster. > Feel free to post these questions if you wish.

I haven't seen the Rainbow News since the June issue but then again,
I'm at college and my dad gave up on forwarding all the magazines.
Hopefully, it will be there by Spring Break (I even wrote an article
for it though it is probably very dated).
As to your problem with BOOT, I believe there is a new version
available for people with DOS 3.1. Check out Mark Bornstein's bboard
at (617) 631-3304. He can connect up to USR HST 9600 baud. If not,
I'll look for it in the next couple of days though I'd have to check
it on my beta-test version of 3.1 (keep forgetting to send my check to
Suitable Solutions).
DO NOT USE THE RAINBOW AT 19.2Kbaud. It won't work past 9600 baud.
In either send or receive, the Rainbow cannot handle the speed (though
it is documented that it can). It supposedly has to do with the
communications chip that they are using (can't remember the number).
I do have MS-Kermit v2.32A available for uuencoded mail. Just tell me
if you want both executables and documentation files. This is the
version that came out in either January or February. One warning:
they are archived using PKZip. Request the beta test version of PKZip
from me if you would like. Send the file requests to me personally at
any of the addresses below.
P.S. As list maintainer: I LIKE ALAN'S POSTS! SO THERE!
P.P.S. Sorry, I just felt like getting a little childish after
reading the debate... :-)

At this speed, you have roughly 2500 clock cycles between received chars--on an 8088, about 425 average machine instructions, so a large interrupt handler or polling loop will not be able to handle 19200. This was done for a DataComm class--a small (4 computer) token ring network. Included in one of our test setups was an IBM XT. Our original intention was to demo the thing (to the prof.) at 2400bps, but with time to play with it we decided to try 19200, and had no problems whatsoever. By the way, the whole thing was written in Turbo Pascal--interrupt handler and all. Tom Colley
