If it is Hayes compatible, AT Lm controls the volume of the speaker with
m=1 lowest volume, m=2 medium and m=3 the loudest.  AT M0 turns the speaker
off and AT M1 turns the speaker back on.  If you want to turn the speaker
off indefinitely, send the modem the AT M0 command and then AT &W (to save
the AT M0 command to volitile memory).
