From: *Hobbit* <AWalker@RUTGERS.ARPA> I wrote a real fast tty-linker a while back that does indeed use timed QIO's with 0 timeout to empty the typeahead buffer into mine. It is *very* fast - When run on the *730*, talking to an Emacs buffer on the 20 where you can't use xoff, it keeps up just fine. You don't have to fix respective line speeds, either, as long as you realize that a 9600- baud screenful snarfed up by the program will take longer to drain out at 1200 when you're dialed up. I intend to expand it considerably when I get time, but perhaps someone else wants to play with it. Macro source is in Rutgers::Red:<awalker>tn.mar, available via anonymous FTP. It ain't pretty, but it works, using a large ringbuffer to hold characters. The only documentation needed is the leading comments. Have fun! _H* -------
