#189444 - Those adaptors
Responding to: Richard Erlacher's previous message
Richard Erlacher said:
Those adapters to which I referred are just a little PCB with that serial port connector, a fully implemented MAX3232A, and a connector through which you can input your low-voltage (3 Volt to 5 volt) serial output from the MCU.

Beware that some of those adaptors don't have a proper RS232 transceiver (MAX-whatever) - they are just a couple of transistors...
