Both TCP/IP and OSI protocols support routing across separate nets as described. TCP/IP is available from several vendors for OS/2 now, and I suspect OSI is too. The drawback is that I don't know of any Lan Managers that are shipped with these protocols as part of the basic package. 3com has a TCP/IP product, but I *think* it costs extra. I'm sure all the others do; these companies don't like to work for free :-). Some TCP/IP products for DOS do not support routing in order to reduce the size of the TCP/IP TSR (and for a variety of other reasons). There is no reason to do this on OS/2, but you should verify that routing is supported before you spend your money. If you mail me directly,I can provide a few vendor names. -JB- ----------------------------------------------------------------------- John Bartas | "We have met the enemy, and he is us" -Pogo NetPort Software |
