I am having trouble sending data from my HP 48SX to my HP 50g via the IR ports. I have both calculators configured for I/O via IR, binary data, CKSM = 3, and 9600 baud (I don't think this matters). I have tried setting the HP 50g to be both an Xmodem server and manual receive. When I issue the send command on the HP 48sx, it goes through several retries, then times out with an error. Similarly, the HP 50g using manual receive tries unsuccessfully to communicate with the HP 48sx.
Any assistance will be appreciated.
Thanks,
Michael
