Mmm, interesting.....!

More reading / GQQGLING for me.

Quick question, we set the mode to 16780 (2400 baud inverted). Does this in tern automatically set the FlowPin to the correct enabled state? 'This enabled state is determined by the polarity of the data specified by mode' (from the manual).

Also what's a reasonable 'Timeout' period in milliseconds for this?

I'll pick up a couple of resistors in the morning.

See you tomorrow.
