You may set the debug level in /proc/sys/net/irda/debug to 1, 2, 3, 4.
root@duckman:~# ls /proc/sys/net/irda/* /proc/net/irda/* /proc/net/irda/discovery /proc/net/irda/irlmp /proc/net/irda/irda_device /proc/net/irda/irttp /proc/net/irda/irias /proc/net/irda/irlap /proc/sys/net/irda/devname /proc/sys/net/irda/discovery /proc/sys/net/irda/compression /proc/sys/net/irda/debug |
There are also some userspace tools irdaping and irdadump to check Linux/IrDA connections.

For some ThinkPad models you have to reboot to the preinstalled M$ OS and activate the IrDA port using the Thinkpad tools. There is currently no Linux tool to achieve that. This will disable your internal serial port (ttyS0)!. The DOS tool is PS2.EXE, as far as I know tpctl doesn't achieve this. It is really important to use this DOS program (ps2.exe) to enable IR. Using the windows tools does not work. Without that the driver loads correctly and everythings seems OK, but the LED does not light bright enough.
