WRITE
The WRITE command is used to put a data byte on the bus and initiate a source
handshake. WRITE may only be issued when the Analyzer488 is in the Talk State.
Handshaking must be set to STEP before using the WRITE command. The STEP
command is not required when using the WRITE command since the handshake is
automatically performed when the WRITE command is executed.
This command does not have a query option.
