Trying to get full duplex TNC functionality for use with FalconSat-3. Manual says the TNC command is "FULLDUP".
So, I connect via rs232 terminal emulator (cable connected to the control head, NOT the RF deck), and enter command "FULLDUP".
All I get in return is the following:
Has it actually worked? Or is the "?" indicating that it has no clue what I asked of it? Note that if I type in "ID" and hit enter, it comes back with "TM-D710GA" (or something similar), so I am definately connected to something. Any suggestions?
