TRACKMASTER
COMMAND PROTOCOL
The Trackmaster Serial Communications Protocol consists of two types of commands, which
are INPUT COMMANDS and STATUS REQUESTS. When a command is sent to the serial
port, it is decoded and executed. The corresponding acknowledgement is then transmitted via
the serial port. The controller transmits acknowledgments and data only in response to a
command.
