The 'old' oEEPROM had a .string property but the new one doesn't.

Using the oBuffer approach doesn't allow a 'prefix' byte to cause the
entire string to be 'parsed'. There is a command for this LCD that
will do neat things like interpret ('parse') "\nHello\tWorld!\n"
doing the CR LF things as expected.

But, it probably only works if it is the first byte in a long
string. Terminating the transaction after every char ('stop'
condition) would probably defeat the process. I suppose using
cv10bit and sending the command followed by a single character MIGHT
work but it is a lot of traffic.

I don't understand why the .string properties were removed. You
know, V5 may live forever!
