Re: Network Device for GS?

Thanks to all who filled me on this GeoPort thingamabob...

I only paid 50 cents for it with all its cables and such in the box but
with no manuals and since I use a regular modem with my IIc and GS so it
was more of a curiousity purchase.

However, it brings something else to mind.

First, as it has 9 pins instead of 8, am I to assume that I would need a
special port in the Mac to run this thing?  Also, if a Mac Classic (sorry
if I am asking this on a II newsgroup) is frying modems, would it mean
that, maybe, that Mac Classic has the corresponding port built in and it
is frying a regular modem?

The reason I am asking is that a friend from our user group asked me to
help a student friend of his with a Mac Classic he bought from a local
university but it fried 2 - 14,400 modems in a row while I tried to get
him on the Internet via ZTerm.  I couldn't figure out why the modems fried
but could it be that this Mac Classic was designed to run a GeoPort
Telecom Interface which could handle the 5v pin?

I am assuming the regular serial port would be removed and replaced with
this GeoPort configuration.  Would anyone have a pinout for either the
GeoPort interface and the Mac serial port necessary to connect to it or
both?

Thanks...
