RS232 Control Signals.
Hi there!
I'd like to know if the RS232 Control Signals are available when
using Bluetooth through Serial Emulation whith the rfcomm program.
I'm writing a program which should detect when a serial device
(which also suports bluetooth) is turned off. The program does its job using an ioctl() call:
ioctl(fd, TIOCMGET, &status);
and then checking for the DSR signal.
It works as expected for the (true) serial port, but when I use
Bluetooth through Serial Emulation with the rfcomm program the signal doesn't change its state, and my program fails.
Are the RS232 Control Signals available?
I'm using the kernel linux version 2.6.10, and the rfcomm program
from the bluez-utils-2.13.
I tryed the rfcomm program with the "bind" and "connect" options.
PS: Didn't find an answer for that question in the Mailing List archieves.
TIA,

I think they are missing. However feel free to send a patch for the kernel that implements support for it.
