[Bluetooth] Store remote modem status for RFCOMM TTY
When switching a RFCOMM socket to a TTY, the remote modem status might be needed later. Currently it is lost since the original configuration is done via the socket interface. So store the modem status and reply it when the socket has been converted to a TTY. Signed-off-by: Denis Kenzior <denis.kenzior@trolltech.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
