Question on Remote Data Access biff 01-02-07

I have a situation where I have some sensors I want to montor manually
at my cabin (say once a week). The sensor data I am gathering is in the
form of a small file, say 5Kbytes. It is simple stuff, mainly
temperature profiles. I have a little controller (STAMP based)
gathering the data; it is not a PC, but it has a USB and RS232
interface. I do not have Internet access at the cabin. Is there an easy
way for me to set up a phone interface to this unit so that I can call
it from my PC and pick up this data? No problem adding a modem. I am
just looking for the simplest way to get the data.

PC Anywhere used to offer telephone access as one of the options for remote
controlling a PC. You might want to give that a browse.

I don't have a PC at the cabin. I just have a small controller board
that puts the temperature data into flash memory. I can download the
data into my laptop over RS232 when I am local. I am just trying to see
if there is an easy way to get access to this file over a phone line.

I just saw this PC:

It's a MicroPC, only 120.00... with that machine your possibilities are
almost endless?

Perle carries several serial to terminal/ethernet devices. Something
like this may work:

http://www.perle.com/products/IOLAN-DS-Terminal-Server.shtml

or

http://www.perle.com/products/IOLAN-SDS-Terminal-Server.shtml

Perle devices aren't cheap (400.00+), but they're reliable and flexible.
If you know how to write C, these devices can run small micro
applications (i.e. to do automated data collection and call out). Perle
provides a SDK for the units. The company I work for uses a IOLAN SDS1 M
for backup dialup to our NOC.

A couple other companies sell similar devices - at a much lower price...
but I'm not sure if they're any good.

So, a MicroPC (or old PC) might turn out to be the cheapest solution to
do what you want?
