Hmm. That is strange. Have you grepped through Eric Raymond's termcap
and terminfo compilations, to see if any terminal supported there matches
such a sequence?

Another thought: Can your trust your source that asserts the existence
of a terminal having such a sequence? (The ultimate proof would be a
serial-line-analyser trace of real output data from the "Rexon"
containing this Control-Y sequence.)

Another thought: a POS system is probably not targeted to an 80x24
format display. It could be a proprietary sequence of some industrial
LCD display controller. You might have to research the application
notes of semiconductor houses which have made chips to control LCDs.

thanks for the info... looks like I have more research to do.
