Yes, however that does seem to generate an error on an m505, where the
same code does not on a Vx running 3.5.x.
The below code will return a serErrNotSupported or serErrBadParam
depending on which port you pick on an m505. (I realize you recommend
using serPortIrPort, but at least *one* of the ports that are
enumerated should be the same as that one, no?)
