I've set up a RAS server, and I want to do some testing, but I don't have two phone lines available, so I'd like to connect two modems directly using a regular UTP cable. [I don't want to use any other method to connect them, since I want to test the modem as well.] It seems to me I used to have a way to trick the modems into starting a conversation, but I can remember what it is....

Hi!
Not all modems can connect on a leased line without a DC voltage, as comes from the telephone exchange. You may have a problem there. Otherwise I think it's a matter of a few AT-commands to get the modems to understand that it is a leased line (AT&L1) and then one modem must initiate the connection. Some modems have a pushbutton for originating a handshake procedure, others require the command ATD, while in the other end ATA should be given. If all goes well a connection can be established.
