great! thanks for your help. btw, rfcomm_sppd(1) _should_ properly
restore terminal settings if it was killed with SIGTERM (-15). if you
kill it with SIGKILL (-9) then you will mess your terminal settings.

i'm pretty sure 'bt-grps' label is incomplete. at the very least you
need 'enable force-scripts' otherwise ppp(8) will not execute chat script.
btw, there is a working example in rfcomm_pppd(8) man page
<quote>
rfcomm-dialup:
# This is IMPORTANT option
enable force-scripts
# You might want to change these
set authname
set authkey
set phone "*99***1#"
# You might want to adjust dial string as well
set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \
\"\" AT OK-AT-OK ATE1Q0 OK \\dATD\\T TIMEOUT 40 CONNECT"
set login
set timeout 30
enable dns
resolv rewrite
set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
add default HISADDR

also some folks prefers to configure access point name, etc. in 'set
dial', but i assume you have configured it on the phone.

i'm not sure about this. also you have 'set speed' in every label.
having it only in 'default' should be enough.

no, i'm pretty sure ppp(8) does the right thing. in fact 'set device
!rfcomm_sppd' worked even before my patch.
thanks,
