I'm trying to get CT set up using 4 com ports (2 are new). I never had
any problems running with just 2, but more computer control stuff euqals
more com ports. Base addresses are standard, and com 1&3 are IRQ 4 (I
think) and com 2&4 are IRQ 3 (at any rate, the com ports share irq's).
The comtsr programs are set up to show the proper IRQ's and base
addresses, but when I try to use the two com ports that share an IRQ,
neither device works properly. Do I need to configure for individual
IRQ's? The software interrupts on the comtsr programs are all different
for the 4 com ports.
Thoughts? suggestions? I'm going to be putting together a 486 over the
summer, and will start off right with an 8 port board! Thanks.
