  For those who are looking for an inexpensive way to link computers over
a distance too great for RS-232, I suggest you contact R.E. Smith, 4311
Tylersville Road, Hamilton, OH 45011.  513 874-4796. 

  I am using two of his RSCOM units here in the W6GO PacketCluster node. 
The 9600 bps link TNC is in another building here, and I have a multi-pair
telephone cable between the buildings which carries telephone lines,
rotator controls and the like.  The link has been running flawlessly at
19200 bps over the telephone cable for over a year.  His specs indicate
that these units will run RS-485 between them at distances of 4000 feet. 

  The RSCOM units are $49 each.  He also sells the modular cables and
plugs to go between the RSCOMs and the computers.  He has several other
alternatives, including an RS-422 converter at $29 each and opto-isolated
automatic baud rate units for much more. 
  I have found Ron to be very accessable and helpful.  If you contact 
him, be sure to tell him Jay O'Brien sent you (I'm not his agent, I just 
want him to know I'm happy enough with his equipment to recommend it to
