Gerhard,

I can't see any point in doing 7171 support as if you have a LINUX, Solaris
or BSD box then you can get ASCII CRT support via TN3270. If you look at my
pics in the VM/370 group:-

http://groups.yahoo.com/group/H390-VM/photos/album/1040167207/pic/list

You can see my TeleVideo Personal Terminal (TV/PT) connected as a 3270 to
VM/370 via my Sparc U60. The TV/PT connects directly to one of the serial
ports on the U60 and runs a "C" shell so I have VI and EMACS on the U60. It
also runs C3270 to connect to Hercules running on my Windows/XP box. I think
I get 14 PF keys (I must admit I don't use it often, the screen on the TV/PT
is small and the keyboard makes a PET keyboard look usable) "hardware" TAB
etc. 

I have used a real 7171 and I would say the above gives almost exactly the
same functionality and feel. For example with the above set-up as the TV/PT
has only a limited set of control codes I had to create new TERMCAP and
TERMINFO entries for it, and I use a custom keyboard map in C3270. I recall
that to do the same on a 7171 required a special program on an IBM PC/XT (or
was it an AT) that extracted config files from the 7171.

Given this I can't see any point in adding 7171 or Yale ASCII support to
Hercules. Perhaps it would be worth providing a cook book for how to set
this up, and seeing if it could be made to work in Windows. I don't see why
it couldn't be made to work on Windows using one of the many UNIX for
Windows tool sets, such as CYGWIN, but as I have a SparcStation20 and a
SparcU60 I haven't really bothered. In fact if it won't work on Windows
directly I could probably produce a 7171/Yale Ascii VMWare appliance that
would run under the VMWare player/or the VMWare server and which would give
the same sort of function. Given that no "X" windows is needed this could be
a very light VM.....
