Getting Started

Install minicom on your Debian1), if you haven't already:

sudo aptitude install minicom

Plug in a USB serial port from the Debian machine to the USB-C power/serial module on the SST-6809.

On the Debian machine, hunt down your USB device pathlist:

ls /dev/tty*

Start minicom with the command line option “-D path” of your USB port device name:

minicom -D /dev/ttyUSB0

Configure minicom terminal timings for 1ms per character and 1ms line ending delays:

[CTRL]+[A] [T]
[D] [1] [ENTER]
[F] [1] [ENTER]
[ENTER]

Create a run-control file to start minicom with these terminal timings every start:

[CTRL]+[A] [O]

Arrow key down and choose “Save setup as dfl” to create this run-control file:

~/.minirc.dfl
# Machine-generated file - use setup menu in minicom to change parameters.
pu msg_ch_delay     1
pu msg_nl_delay     1

Exit the setup menu.

Press the RESET button on the SST-6809 and minicom should show:

ASSIST09

Return to SST-6809
