-> It is unlikely to happen, at present I am using Internet Rex.

Same here.

-> I recently installed VModem and it ties in with PXW. I am looking for Sysops
-> using WINS and PXW to fine tune it.
          
You mean NetSerial.  VMODEM is the same thing, but is a part of SIO for
OS/2.

-> Let me know if your interested and I will send my configs, Netserial has a 3
-> day trial period.

Yeah, I bought NetSerial way back when it was still Com/IP.  I have 10
nodes of PX/WINS listening on my NetSerial ports on port 3456 here.
