Yes Sir,
Rig: Icom IC-746PRO
Poll Interval: 1s
Serial Port: /dev/ttyUSB0
PTT Method: CAT
Baud Rate: 19200
Data Bits: Eight
Stop Bits: Two
Handshake: None
Force Control Lines: (none are selected)
Mode: USB
Split Operation: Rig
As soon as I invoke "wsjtx" the rig goes into transmit and stays there.
I then invoke,
stty -F /dev/ttyUSB0 hupcl
from another window and it comes out of transmit.
Any additional operation I do that would cause a CAT command to be sent,
returns the radio to transmit.
So, I am pretty sure that when the tty device is being opened, DTR is
being automatically asserted. We need to either prevent that or immediately
deassert it.
