[Time-saving (?) information by Zube, January 17, 2000.]

Below are two termcap entries for use with informix.  The first one,
vt100, works very well using teraterm/ttssh on a PC; F1-F10 all work.
The second one, wvt100, works well using a wyse (wy-55) terminal in
vt100 emulation.  To get this to work on (for example), a Solaris 7 box
running informix (and the user is using /bin/csh or /usr/local/bin/tcsh), 
you must have a line that points to the file.

To wit, if you save the second entry into /usr/local/etc/mytermcap, you'll do

setenv TERMCAP /usr/local/etc/mytermcap

somewhere (perhaps in your .login) before your tset line:

set noglob; eval `tset - - -kb -Q -s -m 'dialup:vt100'  -m 'network:vt100' 'vt100'`; unset noglob

Note that I did not have to hack any of the terminfo files to get this to
work with informix.  Also note that they are both called vt100.  This is
by design.  If you wish to use both, save both entries to separate files
and point each TERMCAP variable to each file as needed.  

Anyway, without further ado:

A few random notes:

1) I expunged all the color bits from the vt100 entry because otherwise
it comes up as something like "bright eggshell" on "light eggshell."

2) For the record, real honest-to-goodness vt100s had neither color nor
function keys F1-F10.  They did, however, have PF1-PF4 (four keys above
the keypad) that acted as function keys.  Sometimes termcaps will define 
F1-F4 as PF1-PF4 (this is how the second entry above does it) and leave
the rest out, which is why I saw instances where keys above F4 would not
work, but F1-F4 worked fine.

3) Link MC-5 terminals turn out to be (almost) completely useless under
vt100 emulation because the F1-F5 keys *cannot* (to the best of my knowledge)
be redefined when using a vt emulation.  Instead, these keys do exactly
as labeled on the keyboard, i.e. setup, break, etc.  Indeed, when one tries
to redefine these keys in the setup, the first key available is F6.  
The keys can be redefined under other emulations, i.e. tvi925. 

4) Note that different wyse-55 terminals *seem* (I can't stress that enough)
to emulate vt100 differently.  For example, I had one terminal that worked
fine and another that left garbage everywhere even though the two were
the same model with the same firmware.  After much head banging, if I compared
*all* (I mean every single one, including the tab ) settings and set the
bad one to the settings of the good, all was well.  But I'm not kidding about
the *all* part.
