Make Madrake7.0 Mutlink 2 analog modems

Can,
Anyone tell me or point me to any How-To’s on how to Multink 2 analog modems. I have already been to http://linux-mp.terz.de/ they
have dropped support for this. Please some of you Guru’s I need this badly. can’t get dsl or cable modem but have plenty of analog modems and ISP will let me log in 2 instances. Works great in windows but would like to do in linux.
