S18 - Test Timer; S29 - Flash Dial Modifier Time; S30 - Disconnect Inactivity Timer; S46 - Data Compression Control - Conexant H08-15355F Reference Manual

3.3.3.13 S18 - Test Timer

S18 sets the length of time, in seconds, that the modem conducts a test (commanded by &T1) before returning to the
command mode. If this parameter value is zero, the test will not automatically terminate; the test must be terminated from the
command mode by issuing an &T0 or H command. When S18 is non-zero, the modem returns the OK message upon test
termination.
Range: 0-255 seconds
Default: 0

3.3.3.14 S29 - Flash Dial Modifier Time

S29 sets the length of time, in units of 10 ms, that the modem will go on-hook when it encounters the flash (!) dial modifier in
the dial string. The time can be limited as it is a country dependent parameter.
Range: 0-255 10 ms intervals
Default: 70 (700 ms)

3.3.3.15 S30 - Disconnect Inactivity Timer

S30 sets the length of time, in tens of seconds, that the modem will stay online before disconnecting when no data is sent or
received. In error-correction mode, any data transmitted or received will reset the timer. In other modes, any data transmitted
will reset the timer. The timer is inoperative in synchronous mode.
Range: 0-255 tens of seconds (0-2550 seconds)
Default: 0 (disabled)

3.3.3.16 S46 - Data Compression Control

S46 controls selection of compression. The following actions are executed for the given values:
Range: 136 or 138
Default: 138
S46=136
S46=138

3.3.3.17 S95 - Extended Result Codes Control

A bit set to a 1 in this parameter, in conjunction with the W command, will enable the corresponding extended result code
(see Section 3.5 and Table 3-14).
The +MR, +ER, and +DR settings also control S95 bits 2, 3, and 5, respectively. The more recent settings of +MR, +ER, and
+DR, or host writing of S95 bits 2, 3, and 5, along with the W command setting, determine the corresponding actual result
code reporting (see +MR, +ER, DR, and W commands).
Default: 0
Bit 0
Bit 1
Bit 2
Bit 3
