From 8b6b3da765af9600b5edd8e3e84a20523e975884 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Mon, 14 Jul 2008 20:13:52 +0200 Subject: [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.
