I think I see what you are saying.  That by specifying that the IRQ is hard
coded in the setup line for IRQ3 and IRQ4 like that, you suggest that is where
the conflict arises?  As I understood his post, he had only ONE actual hard
cable connected modem in this setup.  That was the COM1 device.  It normally is
on IRQ4 and has to be known as that way to SIO or SIO2K per what I think I
understand.

I, in fact, use a four port hard coded serial board on this BBS box here. 
While it is an ISA-type card, and it has the ability to define and set up each
COMM port with a different IRQ specified and that is the way I used it, it also
*CAN*, share the same IRQ for all the ports, even in an ISA slot.  That because
of special design and driver work. However, I don't do that common IRQ driver
operation.  I use separate IRQ's for each port.  As has been posted for a long
time, OS/2 can share the same IRQ for different driver purposes.  However that
is dependent on the fact that the drivers which do this stunt have all been
coded very carefully to allow this.  You saw this heavily on the old COMPAQ
computer systems which were shipped with OS/2 long ago and also were shipped
with custome made Adaptec SCSI controller cards, as well as hard disk drives
that were carefully specified to be compatible with these common single IRQ use
techniques.

I never caught that conflict IRQ use in his post.  But SIO and SIO2K both don't
normally care about merged IRQ assignments for multiple internet ports, as I
understand this.  Thus, here are the two different CONFIG.SYS lines for my
system here with four hardware ports and the additional internet ports that
work just fine here:

  DEVICE=C:\SIO\SIO.SYS (COM1:57600,03F8,4,-) (COM2:57600,02F8,3,-)
  (COM3:9600,03E8,15,-) (COM4,02E8,12,-) (COM5,INTERNET:02A8,11)
  (COM6,INTERNET:02B8,11)

Obviously that above is all on one line.  Or in the case of SIO2K here:

  device=C:\sio2k\uart.sys logfile=C:\sio2k\sio2k.log
  device=C:\sio2k\vsio2k.sys logfile=C:\sio2k\vsio2k.log
  vIrqList(1=4,2=3,3=15,4=12)
  device=C:\sio2k\vx00.sys
  device=C:\sio2k\vmodem.sys logfile=C:\sio2k\sio2k.log NoPause nPorts=1
  device=C:\sio2k\sio2k.sys logfile=C:\sio2k\sio2k.log

I don't use a PS/2 style mouse.  It is a serial port mouse that is fed to my
beloved ROSE rack mount KVM switch operation.  Thus in this case the IRQ12 is
available for that COM4 use above which otherwise would be in conflict with the
PS/2 type mouse.

Notice the two internet ports configured in that COM5 and COM6 SIO operation
above that use different ports but the same IRQ?  As far as I know the software
simulated ports in SIO and SIO2K can handle the internet port creation stuff
just fine with a common IRQ specified.  But I don't assign that to an IRQ which
is used elsewhere in hard coded ISA or hardware board level COMM port work. 
And I do not use any of the normal communications ports for an internet port
with SIO either,


--> Sleep well; OS/2's still awake! ;)
