The packet driver does not support multiple instances of a specific
protocol stack. That is, if you want to run FTP and Telnet
simultaneously, they have to use the same TCP stack even if they're
different programs. NCSA telnet won't work here, because you'd have
two completely separate instances of TCP loaded in for the two
distinct applications you're running. You'd need to run something with
a terminate-and-stay-resident TCP to do this properly. The major
commercial TCP products, like like FTP Software's PC/TCP, Sun's PC/NFS
and Wollongong's WIN/PC should all do this for you, with varying
success under various flavors of Microsoft Windows. I don't know of
any non-commercial TCP's that do.
