[ltp] Linux, kernel 2.4.22-ac4/2.4.23 and IRDA

[James McKenzie]

Charles and Steven:

You have to use the DOS based PS2.exe program to permenantly turn on the 
IR port.  You may/may not have to turn off the serial port.  I 
deactivated the modem port to enable the IR port on both my A22p and 
600E to free up a hardware interrupt.

tpctl (as I understand it) will TEMPORARILY do this for you.  I don't 
know if Thomas has modified tpctl to do this permenantly.
