BRIGHTSCRIPT DEBUG CONSOLE
If, while a script is running, a runtime error occurs or a STOP statement is encountered, the BrightSign application will
enter the BrightScript debug console. This console can be accessed from a terminal program using a null-modem cable
connected to the RS-232, GPIO, or VGA port (depending on the player model). Networked players can also be accessed
via
Telnet or SSH .
The console scope is set to the function that was running when the runtime error or
STOP statement occurred. While in the
console, you can type in any BrightScript statement; it will then be compiled and executed in the current context.
Typically, the debug console is the default device for the
PRINT statement.
