I'm trying to set up the config file in Direwolf. The radio is a Yaesu FT290RII and the interface is a Signalink USB.
The Direwolf manual says this about setting up the PTT configuration:
# If not using a VOX circuit, the transmitter Push to Talk (PTT)
# control is usually wired to a serial port with a suitable interface circuit.
# DON'T connect it directly!
# For the PTT command, specify the device and either RTS or DTR.
# RTS or DTR may be preceded by "-" to invert the signal.
#PTT COM1 RTS
#PTT COM1 -DTR
#PTT /dev/ttyUSB0 RTS
Unfortunately, I don't know what that means. Anybody know which one I should use? Any hints, tips, suggestions would be much appreciated.
