If they don't support INT 14 themselves, it will be hard to fake without
a *lot* of fancy programming on a machine which can trap and redirect
accesses to the I/O ports used by COMn (i.e. an 80386 in other than real
mode).  In any case, it seems like you want to create a TN3270 conneciton,
which requires that you use the Dev Kit Telnet library (in 2.05, it is
fancy enough to do a multi-session TN3270) or direct TCP access via sockets
or the INT 61 calls.  The problem is that basic INT 14 isn't zippy enough
to handle block mode and terminal type negotiation.
