This may or may not be specific to the versions of vi and termcap I've
used (Xenix (Sys V.3) on PClones and BSD 4.2/4.3 on ISI machines), but
these versions have a termcap capability for 'visual bell'.  vi uses the
visual bell if it is available; few, if any, other programs seem to use
it.  You can do as I have done, and actually specify a visual bell in
your termcap; or specify a do-nothing sequence for it.  My visual bell
sequence for a VT102 is "ESC [ ?5h ESC [ ?5l", or

  :vb=\E[?5h\E,\E[?5l:

in termcap-speak.  I don't know how to make an empty termcap capability,
but a fair do-nothing sequence is "ESC [ C ^H" (cursor forward, cursor
back),

  :vb=\E[C^H:

In the likely event that you're not using a VT[12]xx terminal, you'll
have to roll your own.  Likewise if your system uses terminfo.

BTW, here are the termcap entries I use; they perform significantly
better for me than the default entries shipped with Xenix, ISI BSD, and
SunOS 3.5, in both speed and reliability:

These have been tested successfully with Amiga HandShake 2.12a and MS-DOS
ProComm Plus 1.1b; they >should< work with real live VT102's, but I
won't make any claims.
