Modem AT Command Set
AT&Q
OPERATING MODE SELECTION
&Q0
Asyncronous direct mode.
l
&Q5
Operations with error corrector. It is automatically selected with
\N command (different from 0 and 1).
&Q6
Asynchronous with buffer enabled (AT/N0).
AT&R
C106
&R0
In asynchronous mode, C106 is controlled according to V25
handshake reccomandation.
l
&R1
In synchronous mode, C106 follows the flow control.
AT&S
C107 (DATA SET READY OPTION)
l
&S0
DSR will remain ON all the time.
&S1
DSR will become active after answer tone has been detected and
inactive after the carrier has been lost.
AT&V
VIEW ACTIVE AND STORED PROFILES
AT&W STORE ACTIVE PROFILE
&W0
Store active profile as Profile 0.
&W1
Store active profile as Profile 1.
AT&Y
DEFINE DEFAULT PROFILE AFTER POWER ON
l
&Y0
Use profile 0 after power on.
&Y1
Use profile 1 after power on.
AT&Z STORE THE X TELEPHONE NUMBER IN A N LOCATION
AT&Zn =X (n = from 0 to 3; X = dialing string from 0 to 35 numbers).
AT\N
ERROR CORRECTION AND BUFFER CONTROL (MNP AND V42)
\N0
Selects normal speed buffered mode (disables error correction
mode). Forces &Q6.
\N1
Serial interface selected. Selects direct mode and is equivalent to
&M0, &Q0 mode operation. Forces &Q0.
\N2
Selects reliable (error correction) mode. The modem will first
attempt a LAPM connection and then an MNP connection. Failure
to make a reliable connection results in the modem hanging up.
Forces &Q5.
l
\N3
Selects auto reliable mode. This operates the same as \N2 except
failure to make a reliable connection results in the modem falling
back to the speed buffered normal mode.
