      Hi Darren,

      rigctld seems to work perfectly, thanks for this.

      To start rigctld for my FT2000 I ran the following in terminal:

      rigctld -m 129 -r /dev/ttyUSB0 -t 4532 -s 38400

      I tested this in fldigi using the info at:

      http://sourceforge.net/apps/mediawiki/hamlib/index.php?title=Net_control

      and it works great.

      How would you recommend me automating the rigctld startup command on system boot?

      Thanks for this, however I don't this this is exactly what I mean.

      In Windows, I used a VSP Manager utility. This had the ability to create a virtual Serial port and pair it to an actual physical serial port.

      So for example COM1 could be paired to virtual port COM11

      Therefore my logging program could be connected to my RIG via COM1, while another application could also connect to my rig using COM11

      So what I'm looking for is simular Linux functionality to pair physical serial port dev/tty4 to a virtual serial port dev/tty12 for example.

      I've done this in Windows using VSP Manager so I wondered if theres a similar utility for Linux.

      Googling around I've come across port simulators but thats not the same thing.

      Apologies in advance if this has been asked and answered before?

      nohup rigctld -m 129 -r /dev/ttyUSB0 -t 4532 -s 38400
      exit 0


      This works when manually executed after making sure the scripts permissions were set to executable.
      I then created a "Startup Application" entry from the Mint main menu. Supposedly this should ensure that this script runs on startup.

      It didn't, so next thing  I tried was to place the following entry into /etc/rc.local

      nohup rigctld -m 129 -r /dev/ttyUSB0 -t 4532 -s 38400

      Still no joy.

      Anyone know how to make this script execute sucessfully on startup on Linux Mint?

      Does ttyUSB0 exist when you call the script? Is rigctl being called at all? Is there an error message? Is there anything in a log file somewhere? Andy MM0FMF

          Manually executing this script works perfectly?

              Run:
              $ which rigctld
              Take the output of that and use the full path to the process.
