Serial Port Downloads to 41CL

[Sylvain Cote]

For serial port diagnostic I normally use a break out box like the one here.
The led's on the box allow you to see if there is a communication (RX & TX) going on and if the handshaking lines (RTS/CTS, etc) are working as expected.
In the case of the 41CL only the RX & TX lines are mapped.
