Ok, so after all the help I tried various things:

Using the null modem adaptor did not fix anything, but what I did notice is that when connected to the device (straight or with null modem), garbage returns to the buffer. If not connected the buffer remains clear. Also, copied HyperTerminal to Win 7 (need the exe file and some .dll files, but a simple copy) and did not establish success when communicating to Hyperterminal.

I will now try two things:

1. Use a different calculator
2. Check what will happen if I connect via HT to the device.

It seems the Serial port of the 50g is not functioning correctly, especially given the inability to communicate with the PC via serial. Thus far only tested on the serial port of the laptop's docking station.


I wasn't able to make working serial connection to hp50 with surveying total stations and gave up. Unlike the hp48 series which all worked flawlessly.
