Language / Serial data stream
« on: February 27, 2021, 10:02:55 AM »
I'm working with a stream of data over a serial COM port. Each 'message' in the stream of data ends with a $04$. Is there way to have the READ directive treat that character as the end of the data to read, so that no other data is read from the buffer? The number of characters in each message is variable, so just using a SIZ= option will not work either.

Language / Blank screen

I'm trying to create a video overlay for information display via a video switcher. Using a 'Key' function, the black area on the screen can be replaced with the underlying video image.
Is there a way to just have a black screen, then add elements of graphics and data to that black screen?
