To help achieve this, use the +.I smdiag +utility. + +This utility can only be used after the interface is started up, i.e. after +ifconfig sm? up. + +The sound driver and the soundcard modem driver are mutually exclusive, i.e. they +cannot both access the same soundcard at the same time. Even worse, the sound driver +reserves the soundcard as soon as it gets loaded. The souncard modem driver however +reserves the card only when the interface is started, i.e. during ifconfig if up. + +9600 baud may not currently work on SoundBlaster cards with DSP revision 4.x, i.e. +SB16 and SB32 AWE. This is because they seem to not be fully backwards compatible. + +.SH "SEE ALSO" +.BR smdiag " (8), " sethdlc " (8)," +linux/drivers/net/soundmodem.c + +.SH AUTHOR +smmixer was written by Thomas Sailer (sailer@ife.ee.ethz.ch). -- cgit v1.2.3
