Does anyone know how to prevent the BIOS from printing ^C carriage return line feed when the control C key is hit. It still displays the ^C even when I have installed my own interrupt handler in vector 23H. Any help would be appreciated.

If you have BREAK set on this will happen during each BDOS call. Otherwise
it will be checked only during normal console access. This means that you
can read and write the console using subfunction 6 (raw i/o) without
getting interrupted.

As far as stopping a displayed control C, I'm not sure that it's possible without writing a keyboard interrupt handler. I have written several int 23 handlers, and I have yet to turn off the ^C display. I suspect that the keyboard interrupt handler displays the offending garbage, and then generates an interrupt 23. If anyone knows of another way to turn it off, speak and be heard. "We thank you for your support" Mr. B.
