HP 50g infrared transfer

[Graan]

Thank you Martin for your valuable information.

The adapter is a ACTISYS IR ACT-IR-220L Plus IrDA to Serial adapter.
There is a sticker saying: "IrDA reference Product" so according to this it should be working with IrDA.

I have 2 of these and tried to transfer serial data between 2 computers (win7 and win XP) with a terminal program and it works fine.
When sending data between the 2 computers I do not see any "garbage" characters and I think it means the negotiation between the adapters works.

I tried different settings on my HP 50G and it does not matter what setting I use I always get the same "garbage" characters (negotiation) coming from the HP 50G at regular intervals.

So apparently the negotiation is not right as the adapter just send the negotiation characters through to the terminal program.

Seems also that the adapter can work either in RAW mode and IrDA mode. I was not successful to install a driver for Win XP. It installed but I did not see any device, but using the serial port I doubt a driver is necessary.
