Problem Solved -- Connecting to Console Port SG-1100 (Linux)
Running Ubuntu 18.04, attempting to connect to the Console Port (USB to Serial adapter in the SG-1100) was unsuccessful. But I found the solution. Hope this helps someone ...
I tried installing putty, but putty would not connect to the serial port. dmesg indicated that the pl2303 was being recognized, the correct driver was installed, and the port was indeed /dev/ttyUSB0. But putty failed with:
(putty:1657) Gtk-CRITICAL ... gtk_box_gadget_distribute ... failed in GtkScrollbar
I finally gave up on PuTTY.
The cu command also failed. I tried
$ cu -l /dev/ttyUSB0 -s 115200
but even if i ran it as root (sudo ...) it failed.
cu: open (/dev/ttyUSB0): permission denied cu: /dev/ttyUSB0: Line in use
lsof showed that there were no processes using that device.
I installed screen
$ sudo apt-get install screen
and then ran
$ sudo screen /dev/ttyUSB0 115200
Success! I'm in.
