ksh (6386) problem

[guy.r.berentsen]

I am running Unix System V/386 Relesae 3.2
on an AT&T 6386 WGS. 

Setting VISUAL=vi on a serial terminal disables KSH
(every keystroke is turned into a <cr>)
I tried this with 2 terminal types (vt100 & 610), so I assume it is not 
a termcap problem.

VISUAL=emacs works fine on a serial terminal, and either vi or emacs
mode ksh editing works fine from the console.

Any Ideas?
