I paired my old Kenwood TS-50 with serial, by using FTDI TTL-232-5V-AJ USB to serial converter. I used ideas from here: http://steeman.be:8080/posts/TS-50%20USB%20Interface/ and here http://i.imgur.com/BmYMq2v.jpg
I have Linux Ubuntu 18.04 and I can detect my serial to usb converter, by using dmesg:
[ 1596.365806] ftdi_sio 1-5:1.0: FTDI USB Serial Device converter detected [ 1596.365857] usb 1-5: Detected FT232RL [ 1596.371078] usb 1-5: FTDI USB Serial Device converter now attached to ttyUSB0
To be sure that I can connect to serial port I first wanted to be sure by checking that connection works with minicom, but it gives me:
minicom: cannot open /dev/ttyUSB0: Permission denied
Despite I am in dial out group and I did all that is written here: https://websistent.com/fix-serial-port-permission-denied-errors-linux/
I can temporary solve that by using it with sudo. That I did, but minicom says, that ir is offline.
I also tried rigctl:
ffu@ffu-desktop:~$ rigctl -m 201 -r /dev/ttyUSB0 -s 4800 -v rig_open: error = IO error ffu@ffu-desktop:~$ sudo rigctl -m 201 -r /dev/ttyUSB0 -s 4800 -v Opened rig model 201, 'TS-50S' Rig command: f rigctl_parse: input_line: f get_freq: error = Invalid parameter
Its looks like from me that apparently something is wrong at OS level, but what?
