S89

Timer to Control Sleep Mode

 

 

Range:

0, 5-255

 

 

Default:

10

 

This command displays the number of seconds of inactivity (no characters sent from the DTE, no RING) in the off-line command state before the modem places itself into standby mode. A value of zero prevents standby mode.

If a number between 1 and 4 is entered for this register, it will set the value to 5, and the inactivity before standby will be 5 seconds. This is done for compatibility with previous products which allowed time-outs down to 1s.

S90

Local Phone Status

0= local phone on-hook

1= local phone off-hook

This register tells the status of the local phone. It is read only.

S91

Line Transmit Level

Range:

6-15

Default:

15

Units:

1 dB

This register is effective only for Japan. It specifies the line transmit level in dB with an implied minus sign.
