Myke,

Thanks for the quick response.

I was hoping to get by with a tone generator, etc.  I am looking for small
size... Also, cost ;-)

OTOH, your modem suggestion is straight-forward, and the cost of low-speed
modems is VERY low now.

Suggestions on the modem interface?  MAX232?

Thanks, again.

In this article, I discuss two different sets of macros for producing "bit
banging" serial routines for the low-end and mid-range PICMicro families.
-------------------------------------------

These serial routines should be sufficient for the serial interface you
require.

Hope this helps,
