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,
