[GreenKeys] ASR33 to Raspberry Pi?

[Andy KN4UCL]

Hi John - yep I'm with you on the github stuff. Way above my pay grade!

Approximate recipe given below, loosely derived from Oscar Vermeulen's
documentation for the very wonderful PidP8 - which also runs a Pi.

1. First - get a Prolific serial/USB adapter off Amazon or eBay (others
work fine, BTW)
2. Cable the serial end of that to your Deramp - tx, rx and Gnd.  Swap Tx
and Rx. Plug your USB connector into an unused Pi USB Port.
3. Assuming Raspbian or raspberry Pi OS -
 Copy the file *serial-getty at .service* from */lib/systemd/system/* to
*/etc/systemd/system/ * (I use sudo pcmanfm for this)
2. Rename that file to
* serial-getty at ttyUSB0.service* - this refers to your serial terminal which
will be ttyUSB0
4. Edit (*sudo nano* to edit the file) the first line in the [Service]
section to read:
       ExecStart=-/sbin/agetty ttyUSB0 110 vt100
 5.  Enable the service:
   *sudo systemctl enable serial-getty at ttyUSB0.service*.
 You should get a "Creating sim link" message, or similar. The service will
now start up at every boot.
 *Sudo shutdown now*
 Power up and test

Good luck!
Andy
