-> as it has been on OS/2, use SIO with vmodem providing the virtual   
   -> modem port for the software to talk to... i still use SIO 1.60D   
      
   I tried the SIO vmodem and it didn't work on warp4, an incompatible   
   dll problem I recall ... or did you mean you're only using SIO with   
   serial ports, and not vmodem?   
      
   I have an inbound telnet solution for PCBoard. It's a reverse telnet   
   proxy, written in PERL, runs on linux. Works for me cause I use a linux   
   box for my router/firewall.   
      
   The PCboard nodes connect to the linux proxy with serial ports and null   
   modem cables, if you have a multiport serial card on the linux box, or   
   via ethernet and a telnet fossil I wrote. The fossil needs Novell TCP/IP   
   from Client32, so your node requires that to run the fossil.  Can be   
   either DOS or Windows 3.1.  I have a Windows 3.1 test box set up with 2   
   nodes working, I think it could do 4.   
      
   It's all free, but a lot of work to get working. People enjoy talking   
   about the good old days and PCBoard, but few are willing to invest the   
   time and effort to make it happen.
