I have an external data logging device using a PIC16F84 that I would like to
send data out over the internet to a similar device. I realize that a modem
is required. I may be able use a PC at either end and send the data through
a serial or parallel port. However what kind of software is required for
direct communications if the PC makes the internet connection?
this months issue of INK has a 1200/2400 baud modem design in it, using the
SENIX chip. BUT...depending on size you need, if you can get away with a
larger box, be cheaper if you can find a couple of old modems. The
'interface' between the phone lines and the modem chip are not that cheap,
and have to be FCC accepted (unless you don't care about that aspect of
PcPlus is a great piece of software that is easily configured.We use it
currently between two modems in the same building thru a telephone pbx system
and it works great.I can't see that you would have any problem with your
setup.Try it , you can always download a shareware version from the net to
try before you but.

on using FNOS, his favorite software for doing this, off the Epson
IM-403 he bought from Timeline. Though I think I'd suggest the EIO $47
486SLC2/50 instead =)

Look like it'll help? FNOS is designed to push files up across FTP
links, basically, so if you are dumping data into a Dos file, you're in
good shape here...
