Greetings Murray!
A long time ago, in a galaxy far, far away, Murray Lesser wrote to Don Guy:

Thanks, but either way doesn't seem to make a difference.

Perhaps you have a memory like mine--it's rather good, but tends to be short 
once in a while. :)
 #ML#> What does SIO report during the boot?
My current line is:
Device=C:\SIO\SIO.Sys (COM1,3F8,IRQ4,,F) (COM2,Internet:2F8,None:IRQ3)        
 (COM3,3E8,IRQ4,,F) (COM4,Internet:2E8,None:IRQ3)
At boot, SIO reports the correct addresses/IRQs for COM1/3 (as well as the 
16550 blurb); COM2/4 are reported as virtual ports, with neither address nor 
IRQ.
 #ML#> In your entries, you have set the IRQ for the DOS version of your
 #ML#> virtual port (vmodem) as IRQ 4 (none:4).  What IRQ is your Telex
 #ML#> program looking for?
Yeah, that's a leftover from when I was trying every port address/IRQ 
combination that I could think of. :)
