Read from this link http://www.xosia.com/~malm/SymbianLinuxHowTo.html
that Symbian does not support IrDA Ultra protocol.

Reason I'm asking, I need to program a simple app that talk to a IrDA board conneted to a door access control system that apparently only supports IrDA Ultra.

Can anybody advise whether the Ircomm or socket classes would be compatible with IrDA Ultra ? Know for a fact that the send via Infra feature on the older 8210 / 8250 phones work with the board, which seems to be implmented using the IrDA Ultra protocol.
