Hi everybody
 
I have three questions related with rfcomm.
 
i did cat </dev/rfcomm0 and now i can read the BT serial , but one time someting happend in the desktop and the welcome message appear "Welcome to gumstix Linux Distribution:..." i want to know how avoid this event, because i dont want to use BT for manage the gumstix.
 
The second question is how is the apropiate way to close the BT link?
 
And the third is how save a specific number of data of the RFcomm?
