I have a situation where I have a method that accepts ONE character at time from a serial source (all ASCII printable).
From this I need to build a string and sent to a display control (think Textarea)
BUT… the serial stream may contain sequences that need to be caught and interepetd and NOT be part of the text output … These will all begin with \ and end with ] and consist of 1 to 3 digts (\93]) … OR be “\B]” \I]" , "\U] or "\X]
The really tricky part is if the sequence begins with TWO \ then its text and not a format command, or it there are more than 3 digits or a character other than B,I,U or X before it encounters the ] character
Basicly this is a “terminal” emulator of sorts, only the serial data comes from the user via keyboard or from an input file, not from a serial port
