What I am talking about is connecting multiple machines using a null modem cable - I know it is possible only to connect two machines and they need to be connected on sio0 (COM1). I'm thinking about the following situation - 1 system acting like a host with a serial port hub, each port of the hub is connected to a different machine on sio0, using null modem cables. This would make the first machine something like a cheaper kind of a terminal concentrator :) What do you think, have someone tried this and is it possible at all? Thanks and regards, DNAeon
