Block Commands
Block transfer commands are used to read and write data in a group of 24 words. The Versapro has only three blocks in
table zero. The block transfer command has to identify the table as well as the block.
A block read command format is shown below.

(E)End of Transmission (EOT) HEX(04)
(L) LRC is the result of an XOR function performed
on all previous character in the messeage.
(D) Delimter marks the end of DATA and signals the
up coming EOT character.
NUL HEX(00) or Backspace HEX(08)*
*If LRC was going to be an EOT HEX(04) then D =
HEX(08).
