Commands
4.7.1. $WAKEUP Modem to Server Wakeup/Keep
Alive
Command Function This command allows the user to configure
the modem wakeup/keep alive parameters.
These parameters control how the modem
initiates contact with its server friends.
Parameters can be selected so that a
wakeup message sequence is executed
every time the modem receives a new IP,
and/or after a requested period has passed
since the previous wakeup sequence has
completed. A wakeup message sequence
consists of sending <max retry> messages
to each server friend in sequence (i.e.
server 2 is contacted after all retries for
server 1 is complete) and is complete when
each server friend has received <max
retry> messages, or upon receipt of an
acknowledge message from a server.
