PROGRAMMING EXECUTIVE COMMAND SET
4.2.4
COMMAND DESCRIPTIONS
All commands supported by the programming executive
4.2.5
SCHECK COMMAND
The SCHECK command instructs the programming
executive to do nothing but generate a response. This
command is used as a “Sanity Check” to verify that the
programming executive is operational.
Expected Response (2 words):
