S-Register Read
Command for displaying the contents of an S-Register (See S-Register Table).
Syntax: ATSn?<CR>
where n is the S-Register to be interrogated (decimal).
Value returned is either in decimal (default) or hex format depending on the setting
of Bit 4 in the S14 register.
S-Register Write
Command for writing to an S-Register (See S-Register Table).
Syntax: ATSn=x<CR>
where n is the S-Register (decimal) and x is the value to be written (decimal, 0-
255).
Result Code Format
Syntax: ATVn<CR>
Modifier Usage
n=0 Instructs the modem to display result codes as numbers.
n=1 Instructs the modem to display result codes as words (default).
Calling Characteristics
Determines which set of responses and calling characteristics are used.
Syntax: ATXn<CR>
Modifier Usage
n=0 The modem will ignore dial tones and busy tones. Dial tone wait time is zero,
and blind dialling is enabled. The modem returns a CONNECT result code when a
connection is established.
n=1 The modem will ignore dial tones and busy tones. Dial tone wait time is zero,
and blind dialling is enabled. The modem returns a CONNECT xxxx result code
when a connection is established, where xxxx is the Tx/Rx line speed (default).
n=2 The modem will ignore busy tones, but waits for a dial tone before dialling. If a
dial tone is not detected within 5 seconds, a NO DIAL TONE result code is
returned. The modem returns a CONNECT xxxx result code when a connection is
established, where xxxx is the Tx/Rx line speed.
n=3 The modem will ignore dial tones. If a busy tone is detected, a BUSY result
code is returned. Blind dialling is enabled. The modem returns a CONNECT xxxx
result code when a connection is established, where xxxx is the Tx/Rx line speed.
n=4 If a dial tone is not detected within 5 seconds, a NO DIAL TONE result code is
returned. If a busy tone is detected, a BUSY result code is returned. The modem
returns a CONNECT xxxx result code when a connection is established, where
xxxx is the Tx/Rx line speed.
