[comp.unix.xenix] Wyse 150 terminals

frankb@usource.UUCP (Frank Bicknell) (06/10/89)

We have a Mitsubishi '386 running SCO Xenix '386.  We have three
Wyse 150 terminals attached to a Computone ATvanage 8$ board.
The versions are:

	Driver version: 4.26/vpix -- for SCO Xenix V (386) 
	Supports 1 board(s) -- 1 found.
	Board 1: firmware version 3.02 ATv

The problem is that whenever I run an application which sends a
moderate amount of cursor control to the terminals, the screen
is occasionally scrambled; the cursor loses its place or some
such nonsense.  It's as if the whole sequence isn't being seen.
It is especially apparent with elm, but also happens with
Professional.

I suspect the termcap entry needs some sort of padding, but all
I have is a wy60 entry.  Has anyone out there had similar
problems with these terminals?

BTW... baud rate seems to make some difference: the problem is
extremely bad at 38Kbaud, and is somewhat abated at 19Kbaud.
The problem looks like dropped or ignored bytes: there is no
"trash" as you would expect with line hits and the like.  I
suspect that the lower baud rate gives the terminal more time to
respond.

Please e-mail responses to 'frankb@usource.UUCP'.

Ah... glad the news doesn't go out immediately.

I tried adding pad to each capability which would accept it.  I
added 100 to most and 500 to cm and cl.  A significant
improvement was noted: Professional works perfectly at any
speed.  However, elm still can be made to foul up, especially on
the main menu.  I'm still open to suggestions: more pad time?
Does elm somehow ignore these parameters?
