[ct-user] CT, Com Ports, IRQ's and headaches

[Alfred J. Frugoli]

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.
