Comment
|
Internally, the Marquee driver uses the NULL character to designate the end of marquee messages. You must specify the alternate character that the driver should use to terminate strings. After you specify the reserved NULL character, you cannot use it in the body of any of your messages.
For example, if you specify ASCII character 255 as the NULL character, then ASCII character 255 will be used internally to terminate strings, and you will not be able to send ASCII character 255 to any connected marquee device.
