       I had a PC-Game, Conquered Kingdoms. It needed a modem
       link for two players.

       A null modem wouldn't work as the program had to see an
       answered ringing tone before carrying on. I had a single
       external modem. I got it to work by plugging the modem in
       one machine, dialling my sisters answerphone, waiting for
       the modem to chirp, picked up the phone outside to hold
       the line open, unpluged the modem and inserted null modem
       cable. Put modem into machine two, put sister answer
       machine on hold, dialled the speaking clock, plugged
       modem into phone line, hang up phone, phone rings to pick
       up holding call machine two starts to warble, unplug
       modem, put null modem cable in and wait. (Also, hang up
       phone). Took about twelve goes but it worked eventually.

       Can anyone see an easier way other than to "adjust" the
       program?

Just do what I did: use a null modem and type RING
