TIP: If you're sending long strings of data, first receive the whole string, then print it on
the LCD.

Receiving a single byte after the "A", then printing it on the LCD, you're missing a TON of
serial data during LCDOUT. And you only have 1 synch character at the start of each
string.

Also ... give the receiving end time to place everything on the LCD before sending the next
string. Imagine someone handing you ten gallon buckets of water every 2 seconds, with
you having to pour it through a straw into another bucket, and trying to keep up...;o)
