I am just about finished with "VersaTerm-HP", good-ole VersaTerm with the
VT100 emulation replaced with an HP 2621+ emulation, ENQ/ACK handshake, local
editing, etc...

There is a problem with "Mac XModem" (macput/macget) though when you
are emulating a HP262X.  The <ESC>a sequence tells VT100 VersaTerm to
start Receiving a file... BUT an HP2621 does an "absolute cursor sense"
when it sees an <ESC>a, so we need another sequence:

   I propose,    <ESC>?     . Since this means that macput/macget needs to
be modified, I hope that we can do this once an for all.  A grep of our
termcap says that only the Concepts use this sequence, as well as the <ESC>a.
So I hope <ESC>? will be "safe" choice.

Currently I do a getenv() in macput/macget and test the TERM variable to
decide on either an 'a' or '?'.  On other systems a flag might be used, or
just a seperate program.

If anyone has a better suggestion of a sacred sequence, please let me know,
or else I will go ahead with the <ESC>?.
