[net.micro] modem/telephone problems

done@teklabs.UUCP (07/08/83)

This might be more appropriate for net.micro.atari, but I thought it is of
general enough interest to put here.

I recently bought a modem for my Atari 800 computer made by Microbits in
Albany, Oregon.  The modem is designed to be inserted into the loop which
connects the telephone base with the receiver (obviously, this requires
modular plugs on both ends of the coil cord, although modifications are
possible for non-modular phones).  Unfortunately, I discovered that GTE
phones do not work with this modem (perhaps the signals lines inside the
coil cord are rearranged), and I couldn't get a dial tone in voice mode.

Next I borrowed an old Bell rotary phone, and this worked like a charm.
But, when I shelled out the money for a new touchtone Bell phone, the
modem wouldn't work properly, even though it worked ok in voice mode.

Finally, I made an exasperated call to Microbits, and they didn't have the
foggiest idea what could be wrong, either with the GTE phone or the newer
Bell phone.  I am hoping that one of you phone gurus out in netland will
have a good idea of what the problem is here.  It's very discouraging when
the folks who designed the modem don't even have a minimal suggestion.

By the way, I have since gotten rid of both the modem and the new Bell
phone, and I am awaiting Atari's new direct-connect modem to be available
in August.
