I would appreciate any word about theis public domain product.
Apparently ity was written/distributed by someone called
Ziff-Davis.  I have sketchy details, but it is a product that
clears out "clogged" data from printer/modem ports that can 
be left from careless applications.  Any data as to a possible
ftp site for this would be appreciatred.  E-mail responses would 
be most appreciated...
