Is what you mean like this ? computer <---> modem <----//----> modem <---> computer ^ |_ the connection you want. Well if so, here's a trick which Doreen Pechey(*) showed me: just use a telephone T connector and ignore the plug end of it. If you have such things in the USA that is :-) I refer to connectors that allow you to telephone 1 ---> T1 |----> phone socket telephone 2 ---> T2 just plug the modems into the T1 and T2 ends of the connector and ignore the plug that would go into the phone socket. No twist is required. Doreen uses this trick when giving courses teaching people how to use modems :-) My goodness, what inefficiency ! (Yes, I know this word isn't en vogue now that it is alright to have a screen blanker which uses 1 MByte+ of memory, but those of us who learned to program on computers with 512 Bytes (That is Bytes, no k, no M !) still have conditioned reflexes which force them to respond to posts like the above :-). If you want to connect 2 computers, and don't have a network then use a null-modem cable for $9.95. Null-modem means that you use 0 modems. It connects directly between the serial ports of your 2 computers (those ports, to which usualy the modem is connected) and allow you to use transfer rates orders of magnitude higher even that the advanced modems discussed in this group.
