IR Port (COM4) is not working

[Guest Claudio]

I'm trying to achieve an infrared connection between my SPV and another IR device. I use raw infrared, not IrDA. I have some experience doing this on the Compaq iPAQ. The WriteFile() function to the specially configured COM:4 generates an output to the infrared port.

Unfortunately, on the SPV Smartphone, the port is not working properly:

As soon as I send one byte or more, the SPV sends automatically the byte 0x0C for about ten times to the port, and after this "overture" the real data. The reception is not working at all.

Does someone have experience using the IR-Port (or another COM-Port) on the SPV? I'm suspecting the serial driver on the SPV because I remember a bug on the iPAQ 3970(which has now be fixed) as well, that caused problems with the IR-Port.

Any ideas?
