To answer the above, yes Warp 4 will allow comm ports at 115200 as long as 
your OS2 app can open to that speed. SIO doesn't care what speed your app can 
talk to the port, the port always talked the right speed to the modem. 
Reasons to keep SIO for Warp 4:
   1) more than 4 ports
   2) share IRQs on ports that are in the same chip (most PCI mbds and some 
of          the better IO cards these days)
   3) fossil support
   4) virtual modem support
   5) ability to tell DOS whatever it needs to know to work without regards 
o
         reality (you need all the DOS apps to use com1/IRQ4 go ahead
   6) ability to monitor the ports and control the locked rates etc...
As I depend on all but number 5 I will keep my 8 port SIO.
