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: HK|vt102H|HandShake|Amiga HandShake VT102 emulator:\ :li#24:co#80:cm=\E[%i%d;%dH:ho=\E[H:ll=\E[24H:up=\E[A:UP=\E[%dA:do=^J:\ :DO=\E[%dB:le=^H:LE=\E[%dD:nd=\E[C:RI=\E[%dC:sc=\E7:rc=\E8:ce=\E[K:cd=\E[J:\ :cl=\E[H\E[J:im=\E[4h:ei=\E[4l:mi:al=\E[L:AL=\E[%dL:dm=:ed=:dc=\E[P:\ :DC=\E[%dP:dl=\E[M:DL=\E[%dM:sf=\ED:sr=\EM:sb=\EM:cs=\E[%i%d;%dr:mb=\E[5m:\ :md=\E[1m:mr=\E[7m:so=\E[7m:se=\E[m:us=\E[4m:ue=\E[m:me=\E[m:ms:\ :vb=\E[?5h\E,\E[?5l:as=\E(0:ae=\E(1:ks=\E[?1h\E=:ke=\E[?1l\E>:vt#3:\ :is=^O\E[1;24r\E[24;1H:rf=/usr/lib/tabset/vt100:\ :rs=\E>\E[?3l\E[?4l\E[?5l\E[?7h\E[?8h:pt:bs:am:xn:xo:kb=^H:kd=\EOB:kl=\EOD:\ :kr=\EOC:ku=\EOA:k1=\EOP:k2=\EOQ:k3=\EOR:k4=\EOS: HS|vt102Hs|HandShake-s|Amiga HandShake VT102 emulator w/sysline:\ :li#23:ll=\E[23H:cl=\E[23;80H\E[1J\E[H:hs:es:ts=\E7\E[24;%dH:fs=\E8:\ :ds=\E7\E[24H\E[2K\E8:is=^O\E[1;23r\E[23;1H:tc=HandShake: 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.
