Yes, I use it with my cellular phone to connect to the Internet.

This all looks correct.

Which device are you connecting to?  /dev/irframe0 or /dev/ptyXX?  The
ircomm program connects the irframe device to a pseudo-terminal.  I
typically invoke ircomm as:

$ ircomm -d /dev/irframe0 -y /dev/ptysf -m 9600 -Y

I can then use /dev/ptysf with cu to test AT commands, pppd to obtain a
packet-data connection or a SMS sending application.
