First of all, I want to thank everyone who sent me E-mail regarding my
problems with the Modem pack I detailed three weeks ago.
 
Well, now I STILL have a problem. I took everyone's advice and wrote the
whole bloody terminal program in Assembler. I use a BASIC driver for it
to set up my parameters, but once a carrier is detected, the assembler
program takes over and holds control until I press SHIFT-CLEAR. Alas, I
still have the same problem. The moment I mess with the Modem's registers
to send or receive data, the cartridge's terminal program takes control,
just as though I had issued an EXEC &HC000. What can be the problem? I do
call two BASIC routines (POLCAT and CHROUT), could that be the problem?
I masked all interrupts (except NMI ;} ) like the manual said to. If anyone
requests it, I will send my source code to help. Once again, thanks to all
you 6809ers out there!
