Thanks for your reply !

This code is almost the same as what I have tried before I started the thread.
I'm receiving the bytes at 4800 Baud (Mode $BC)

It works fine for just receiving characters (no control bytes) and displaying them bytewise.

If a control code like $FE,1 (clear display) is received and data is received right after the control bytes the display is cleared but the next 1 or 2 characters to be displayed get lost.

The CLEAR command takes too much time for the display to handle characters send right after the command.

btw. you don't need to include modedefs.bas if you are not using modes defined there.

regards
