M n Monitor Speaker Mode{ XE "AT commands:M" }{ XE "Monitor Speaker
Mode command" }
n = 0, 1, 2, or 3
Default: M 1
The M command allows you to control the modem speaker mode.
M0 completely disables the speaker.
M1 causes the speaker to be on only until a carrier signal is detected. This is the
default. It allows you to hear the initial dial tones and handshake “squawking”
when dialing out, for example, which lets you know activity is taking place and
when a carrier signal has been detected (the “squawking” stops).
M2 causes the speaker to remain whenever the modem is off-hook.
M3 causes the speaker to remain on until the carrier is detected, except while
dialing. This means the speaker is on during the dialing, so you hear the dialing
tones, but turns off during the handshake, so you eliminate the “squawking”.
