4.1.2 Serial Interface Operation
The host computer initiates serial interface link operation; it transmits either
a command or a query to the Model 234. The Model 234 stores the
characters in a 16 character buffer until the carriage return (CR), line feed
(LF) terminator sequence. After receiving the terminators, the Model 234
responds to a query, if present, and stores the new input parameters.
Queries result in output of the requested data immediately following the
processing of the command and terminator sequence.
Communication is
half-duplex. For example, the command string TAG 234-1 sets the
electronic tag number of the unit to 234-1. The query TAG? returns the
electronic tag number of the unit.
