Baffled with soudnmodem

Despite having been an avid Linux user for several years, I am somewaht confused about the proper way to set up soundmodem on SuSE 7.3 I read the various sources of information about soundmodem and AX25 in general, but unfortunately the documentation does not always refer to the current software, particularly the variants of the sound system. I would be grateful if any of you could provide me with the steps required to get soundmodem working under SuSE 7.3 including what part of the sound system should and should not be loaded. Thanking you in advance, 73 Sylvain Houle, VE3SHO
