I am looking for a modem kit to put together for a Manufacturing
Processes course here at Cal Poly.  If anyone has built their own
modem and would be willing to share the schematic and other info for
it, I would appreciate it.  I would also be willing to pay for it.

Plagiarism is not a factor here as this course emphasis production and
not design.  I will have to put the design onto our CAD/CAM system for
production so legible schematics are needed.

If you know of a design published in any magazines or kits available,
these would also work.

I am looking for a design for a 9600 bps (or 2400) external modem with
it's own power supply contained in it and working led's providing
status information.  The connection would, of course, be through a
RS-232 port using serial communications.

Hayes compatible command set would be nice, but is not necessary.

Please send all responses to mjarvis@polyslo.calpoly.edu

Thank you.
