Terminal server? (Kinda.)

[Jerry Feldman]

Do I read you correctly that you are going to individually wire each
RS232 port?
How are these locations going to be connected to the home office. I
think that RS232 is a max of 50 ft or so. Or are these going to be
connected to some in-store modem connected to the phone system or
possibly with an in-store computer connecting to the Internet or to the
home office via dialup.
Back in the early 1970s we put POS (DEC PDP-8M) devices into all the
Burger King stores with a low cost modem card.
