Re: Advice on serial port communication

Hi Stuart and David,

Thank you to you both for the amount of time and advice you have provided.

I am away from my BBB for a couple of days. As soon as I get back to it,
I will try out a few things, based on advice from both of you.

I will update after that.

Thank you.
