Commonly called line noise, the spurious characters that
appear on the screen are usually from the central office of the
phone company. It can make a big difference whether you call out
or someone calls 'in'. Also there is a difference between
calling different areas (area codes or exchanges) as different
equipment will be involved. Calling the phone company will rarely
do any good, because the problem is not on your line.
However, because the problem is not rare, (in fact common in
some places), operators of BBS and other modem users have come up
with a cheap simple solution which works most of the time.
You can make (or have made) a 'noise filter'. Parts are less
than $2.50. You plug it into the modem 2nd jack. If you are using
a phone in the 2nd jack then a "T" adapter (about $2.50 at Radio
Shack) will let you put the 'filter' on and still use the phone
in that jack. (I have never seen a 'noise filter' for sale. The
only device I ever saw that claimed to stop noise, cost more than
$45 and did nothing at all).
