hello all,

I have three things that require the use of serial ports.  I have a mouse
an internal modem, and a printer (actually an old teletype modem used as
a printer and hooked up through a com prot).  I would like to be able to use
all of them at the same time.  However, most things I have read indicate
that com1 & com2 share IRQs with com3 & com4.  Does anyone know how to
set the I/O board to use 4 IRQs for the 4 com ports?  I realize the
detailed answer needs more hardware information, but I'm not sure what
type of information you'd need.  If you have any answers, or can even
point me to a good reference please Email or post the answer.

Thanks,
---
