Table 9. Extended AT& Command Set (Command Defaults in Bold) (Continued)
Command
Action
&T5 Initiate transmit as answering modem with automatic data generation. Modulation, data rate, and
symbol rate are set by &H, &G, and S41. Data pattern is set by the S40 register. Continues until the
ATH command is sent after an escape into command mode. Data is also demodulated as in
ANALOOP, and any bit errors are counted to be displayed after the test using &T0.
&T6 Compute checksum for firmware-upgradeable section of program memory. If no firmware upgrade is
installed, &T6 returns 0xDE5C.
&Xn Automatic determination of telephone line type.
&X0 Abort &x1 or &x2 command.
&X1 Automatic determination of telephone line type.
Result code: WXYZn
W:
0 = line supports DTMF dialing.
1 = line is pulse dial only.
X:
0 = line supports 20 pps dialing.
1 = line supports 10 pps dialing only.
Y:
0 = extension network present (PBX).
1 = outside line (PSTN) connected directly.
Z:
0 = continuous dialtone.
1 = make-break dialtone.
n:
0–9 (number required for outside line if Y = 0).
&X2
*Y2A
Same as &X1, but Y result (PBX) is not tested.
Produce a constant answer tone (ITU-T) and return to command mode. The answer tone continues
until the ATH command is received or the S7 timer expires.
