I decided to take another look, and here is what happens:
If you have the 'persist' option in /etc/ppp/peers/<connection name>,
pppd will reconnect after errors. To reconnect, it closes the device then
reopens it. With gsm0710muxd, when /dev/pts/N gets closed it is
deallocated. Then, pppd is trying to reconnect to a device that doesn't
exist.
A hack-around for this might be to turn off the 'persist' option and make a
script like:
identvar=$(date +%s)
while true; do
# code ripped of from somewhere to get a mux device
ptsvar=$(dbus-send --system --print-reply --type=method_call
--dest=org.pyneo.muxer /org/pyneo/Muxer org.freesmartphone.GSM.MUX.AllocChannel
string:$identvar | grep string | awk -F '"' '{ print $2 }')
[ -z "$ptsvar" ] && exit 1
logger -s "gprsd.sh[$$]: starting pppd using $ptsvar"
pppd "$ptsvar" 115200 call <connection name> nodetach
logger -s "gprsd.sh[$$]: connection closed, waiting 10 seconds"
sleep 10
done
