John,
Thank you very much, this clue was just what I needed.
The old serial manager works fine on my Visor and my Palm IIIc. It is not
working on the Palm 505 (PalmOS 4.0) though, because serCtlIrDAEnable is no
longer supported. This is at least what the SerControl call tells me.
The new serial manager does not complain about srmCtlIrDAEnable, but it is
appearently not working. I don't think it is a hardware problem with my 505
as IrComm is OK. The new serial manager returns serErrBadParam when I try to
set srmCtlRxEnable. So maybe this is where the problem is.
