MVI56-BAS is running a program connected to a device that sends data and sometimes the BASIC program is changed. How do I prevent this?


It is possible that if you have a basic program running in your MVI56-BAS and you have the port 1 connected to a device that periodically send data, sometimes the basic program may be changed. This can happen if your device sends the ^c (Ctrl C) character (ASCII 03) to the BASIC module, changing the mode of the basic module to program, then the next received characters can be accepted as a new program line.

To avoid this you can use the call 19 (disable ^c checking) at the beginning of your program.
