The configuration of the cable used to connect the modem to the MUT is not important. Any serial data cable should have the connections required by the debug kernel. Just make sure you don't use a null-modem cable. You will either need a 25-to-25 pin cable (for connection to the built-in serial port on a PS/2), or a 25-to-9 pin cable (for connection to a 9-pin serial port).

Required connections for remote debug cable:

Notice the 25-to-9 pin cable reverses pins 2 and 3. Do not confuse this with a null-modem cable - the signals on a 25-to-9 pin cable are normally reversed.
