There seems to be ETX, EOT, EM, FS... in ASCII but I dunno how portable that 
is.

If you control both processes you can use whatever convention you like. 
Other than that it'll be difficult.

Btw, why do you want to do that?  A named pipe where you want to disconnect 
a listener but keep the pipe is about the only reasonable scenario that I 
can think of at the moment.

Kind regards
