what for are you using the -c2 option. The DTP94 is an USB instrument and should work without that option.
The -c option selects the instrument or communication channel. There may be more than one USB instrument available on the system, and Roger was selecting the second instrument. I could make it so that all serial channels were interrogated so that the instruments on them are listed, but this would slow down the program startup, and could mess up gear that's not an instrument and is connected to a serial channel.
