serial port
.
Sniff Mode 3
When status register S143 is set to a value of 5, the unit works the same way as sniff

This register applies only to Remote modems and is
only effective when S143>0.
Defines sleep duration for up to approximately 18
hours.
Two conditions will awaken a Remote:
1. sleep duration time has expired, or
2. incoming data on local data port.
When a sniff mode is selected (S143), the modem will
start its sniff cycle when the Sleep Time expires or will
wake up completely when there is data on its local data
port.
Values
S145
Wake Time

0-65535
10
Applies only to Remote modems and effective only
when S143>0.
This register determines how long a modem will stay
awake after the local data port and radio links become
idle.
When the modem is idle for the amount of time
specified in S145, it will go to sleep; it will go to sleep
immediately if ‘upstream’ unit is offline or goes into
sleep/sniff mode.
