[mod.telecom] Problems with Racal Vadic 3451

Mly.G.Pogo@MIT-OZ ("Bob Soron") (12/19/85)

After having used an el cheapo 300-baud modem with my Apple ][+,
I recently traded up to a used Vadic 3451 modem, with the Apple
Super Serial card.

The problem is that whenever my roommate picks up his phone --
it's a completely separate line -- the Vadic disconnects.  When
he dials his phone, the Vadic starts making the clicking noise
it makes when it dials.  I have no trouble going on-line if he's
already on the phone, but when he hangs up, the Vadic disconnects.

He's using a Western Electric phone (a Mickey Mouse, for what it's
worth).  The previous owner never had any trouble with it, and he
is as trustworthy as a person can be.  My guess is shielding, but
I'm a complete layperson on these matters.  If anyone can give me
a solve or even a more definitive guess, I'd surely appreciate it.

I'm not on the list, and read the bboarded digest irregularly;
please respond to me directly.  Thanks in advance.
