So are you implying that if I do not go through RFCOMM and all the sockets stuff, I can actually open /dev/rfcomm0 and get back a file descriptor just like any other serial port?

So are you implying that if I do not go through RFCOMM and all the sockets stuff, I can
actually open /dev/rfcomm0 and get back a file descriptor just like any other serial port?

Thanks

You sure can.

You can of course use the code provided by Manuel too but then your
code won't work without rfcomm/bluetooth. The nice thing is that if
you keep it generic you can test your application using any old
serial connection. Or use a pipe in the filesystem etc..

Caveat: I can't get mgetty to work by feeding it /dev/rfcommX though :
( It should work, must be one of those things ;)
