Sure sounds like a SET HOST bug to me. I believe SET HOST packages up the terminal I/O request on the remote system and ships over to the local RTPAD, where the appropriate local QIO is performed by RTPAD. There may be room for a bug or two in all that. Has anyone tried the simplest case? Something like PTY.PAS which generates it's own output lines to get rid of extra variables like the PTY driver? Another thing that's been reported to me is that PTY.PAS does not work inside a VT220 window on a VAXstation, although it does work if you log into the VAXstation with a direct or LAT terminal. Do single-char reads not work in a WTA device? Does Asbed's PHOTO work in that situation? /Kevin Carosso kvc@engvax.scg.hac.com Hughes Aircraft Co. kvc%engvax@oberon.usc.edu
