I've been working on a program for some time now and the correct answer seems
to be evading me completely.. So, here's the problem. I've written a SMALL
terminal program in Assembly language and I KNOW the ports are being opened OK
with the calls to the Amiga.lib functions _CreatePort and _CreateExtIO. I open
the console the same way (_CreatePort & _CreateStdIO instead). Anyway, while
in the "main" loop chunk of code where I check for incoming characters from
either the serial port OR the console port, the system seems to "ignore"
console requests at higher baud rates UNTIL ALL of the serial requests have
finished completely.. I can make it do this easily on my A1000 by talking to
my modem and typing "AT$" (U.S. Robotics 2400 Courier) and it will spew out a
menu of all the commands it knows (a whole screen full). So, while processing
the serial requests, I can use the CheckIO function to check the current
status of the Console port and it ALWAYS comes back with a zero (I/O
imcomplete), UNLESS I'm at 300 or 1200 baud! At 2400 baud, it will wait to
process the console I/O AFTER it has finished with the serial I/O first...
Does this problem sound at all familiar?? I thought it might be a priority
problem with the task, and that didn't fix anything. I also fooled around with
port priorities, but that didn't help either.. If you've got ANY ideas, let me
know...
Thanks in advance..
