I'm trying to communicate between a microcontroller, and a mobile phone.
I have an infrared device that establishes a connect, but seems to be unable
to send the AT commands.
The IR device manufacturer said that as long as the device communicates at
the IrCOMM 9 wire level, it should be able to receive the AT commands.
The mobiles I am using are Ericsson T310, and a Nokia 6310i. Both devices
connect to the IR device, but appear unresponsive to AT commands. Both
devices will work with a different IR device that requires a Windows driver.
Any suggestions on what is going wrong would be greatly appreciated.
