Commands
The commands are a series of ASCII characters with an
alpha command and one or two numeric operands followed
by a carriage return, ASCII 13. The commands may be
spelled out though only the first character is significant. i.e.
READ 123 may be abbreviated to R123. Every command
has a response to acknowledge that it was received correctly
and to provide data requested. For high reliability systems
there is an error-checking protocol that will ensure proper
command data transferal. See “Error Checking Protocol”.
