Before I made AX.25 work with my kiss TNC's, my mouse (run of the
mill serial mouse) worked OK. Now it does not. Clearly, IRQ4 seems to
be taken by kissattach on COM3 (ttyS2, excuse me) and I have to solve
that dilema.
For a time I was using a modified MS-400 card (4 serial ports)
modified 'a la AA4RE' for use with BPQ 4.08A, and a single shared
hardware interrupt for COM3 to COM6 using a 4 input CMOS OR gate
with a line from each UART chip to a single IRQ line out of the OR
gate. It worked fine. OS was MSDOS 6.22, and Desqview 2.60 as
multitasker.
I wonder if that COULD work under Linux, or if somebody uses it under
Linux. I could attach the TNC's to a single IRQ and leave COM 1 for
mouse and COM 2 for CAT.
Cheapo but functional solutions welcome.
