Hi Marcel,
Here is the patch we talked about,
This was the original thread :
http://sourceforge.net/mailarchive/message.php?msg_id=36194832
It 's an option to make rfcomm kind of persitent.
It can be used like this :
rfcomm --raw watch 0 20 cat {}
or rfcomm --raw listen 0 20 cat {}
Now, you can connect from another computer like this "rfcomm --raw
connect 0 <addr> 20" and any incoming rfcomm data will be displayed.
Typing "echo test >> /dev/rfcomm0" on client will display test on the
other computer.
When the client disconnect :
- The "rfcomm listen" will exit
- The "rfcomm watch" will restart listening with the same parameters.
Regards,
Frederic.

can you please fix up your usage (or lack of) whitespaces. I like to
keep all code in sync with the coding style.

Hi Frederic,
The patch is now in the CVS. Could you provide a patch to the manual
page (rfcomm.1) too?

Hi,
Attached is a proposal for the manpage.
It looks like this:
listen <dev> [channel] [cmd]
Listen on a specified RFCOMM channel for incoming connections.
If no channel is specified, it will use the channel number 1,
but a channel must be specified before cmd. If cmd is given, it
will be executed as soon as a client connects. When the child
process terminates or the client disconnect, the command will
terminate. Occurences of {} in cmd will be replaced by the name
of the device used by the connection. This command can be termi‐
nated with the key sequence CTRL-C.
watch <dev> [channel] [cmd]
Watch is identical to listen except that when the child process
terminates or the client disconnect, the command will restart
listening with the same parameters.
Frederic
