First steps in re-purposing my old Raspberry Pi

First steps in re-purposing my old Pi: connecting to it via the serial console. Since the Pi’s serial console uses TTL levels, I used a TTL<->RS232 converter I bought locally ( wiring from Pi to the converter was straight (RX-RX,TX-TX,VCC-5V,GND-GND) which means the converter I used seems to have incorporated the reversing of the TX and RX lines for “null-modem” operation.

The Pi sees the serial console as /dev/ttyAMA0, running at 115200 8N1.
