Using IBM's mainframe TCP-IP implementations and OS/2 Extended Edition's
TCP/IP, what physical layers can be used?  I assume Ethernet at minimum,
but what about token ring, and what about SDLC since that is how the
vast majority of PCs are linked to mainframes?  Also, what about the case
where a PC goes through a gateway that emulates a 3174 and is connected
by modem to a 3725?

Thanks,
