Just a quick post today on how to use the psion 5mx as a serial terminal for your linux machine.
- Connect your psion 5mx to a serial port on your linux machine. If you have none, a USB adapter works fine.
- Find the serial port the psion is on. For me this is /dev/ttyUSB0.
- Make sure your user can access the serial port. For me on arch linux this was a case of adding my account to the
- On the psion, make sure remote link is disabled. (Ctrl-L on the system screen, make sure it's off.)
- On the psion, open comms. Press Ctrl-K to open the connection preferences. These are the settings I use:
- Comms port: Serial Port 0
- Data bits: 8
- Stop bits: 1
- Parity: None
- Leave "Handshaking" as-is.
- Pick a baud rate. Lower rates are slower but more stable, higher rates are faster but potentially more error-prone. Experiment!
- Back on your linux machine, run
stty -F <Psion Serial Port> <Baud Rate>to set up the serial port.
- The Psion, by default, uses a VT100 emulation, but the emulation isn't great.
export TERM=vt100still works best, though.
- The Psion is now ready to be used as a serial terminal! For example, to run a shell on it, I'd use
zsh < /dev/ttyUSB0 > /dev/ttyUSB0.
- Enjoy a fairly pointless and not great serial terminal!
