Hi all, Here is the problem statement : ( And let me add that this problem is being faced by me, and I am the proud owner of the antique hardware mentioned below :) ) There is an old machine without a PCI interface (has only ISA) and a realtively newer one with both ISA and PCI. The quest is to network both. One solution is to find 16-bit (ISA) n/w cards and find the drivers for them, get a cross-over cable and be happy connecting them. But I personally found it impossible to find a n/w driver for 16-bit cards. (If anyone can find one, i'll be glad :) ). The other is what the subject line suggests. Make a point-to-point network using PPP (Point-to-Point Protocol) over serial port. Does it sound exciting? Anyone interested? TC PS : If anyone found *anything* that he/she did not understand in the lines above, or is not familiar with it, shoot questions. For ex, "what is networking" and "what is a serial port" are two very good questions.
