Ticket #1289 (closed defect: wontfix)
PSC (power saving commands in muxer mode) seems to be broken

|Blocking:||Estimated Completion (week):|
the gsm.07.10 spec chapter 220.127.116.11 describes that the modem sends a PSC request
to indicate sleep. in case of wake up it sends another PSC request. i've never
seen any PSC request from the modem.
none the less the modem goes to sleep and does not allow sending packages
anymore. you have to wake up it in the way described in chapter 5.4.7 sending
flag-chars until the other end response with a flag-char. i never received any
such char from the modem.
just sending several flag-chars before any package wakes up the modem most of
the times but not always. in some cases the muxer runs into a timeout and the
modem can't be activated anymore.
i'm the author of gsm0710muxd and that's the area where i see this behavior.
