Digital Marshalls
>Environment:
FreeBSD spammie.svbug.com 3.5.1-RELEASE FreeBSD 3.5.1-RELEASE #0: Wed Sep 13 20:07:41 PDT 2000 jessem@spammie.svbug.com:/usr/src/sys/compile/GATEWAY i386
>Description:
vidcontrol has no error code other than when it prints a usage
message. This makes it difficult to test via scripts. The attached
code adds error codes.
Caution is advised as the changes have not fully been tested.
>How-To-Repeat:
>Fix:

> SCRNSVR_POS = 7, CURSORBADARG = 8,

> CONS_ACTIVATE = 11, MOUSEBADARG = 12,
> MOUSEBADARG2 = 13, SHOW_ADP_FAIL = 14,
