sure

please find attached patch. the patch will put stdin/stdout into 'raw'
mode when no tty was specified. it should fix the problem you were having.
keep in mind that there is no escape sequence, so you have to kill
rfcomm_sppd(1) by hand to terminate the session.
could you please try to use rfcomm_sppd(1) in both stdin/stdout mode and
in 'set device ...' ppp(8) mode.

could you please post /etc/ppp/ppp.conf entry you where using with
rfcomm_pppd?
thanks,
max
