[net.general] Short Haul Modem Query

wall (09/07/82)

   I am very interested in anyones information / experience with any
RS 232 short haul modems. There are only two vendors that I know of: Develcon
in Pennsylvania, and Remark  in New York. The Remark is a problem in that it
requires the RS 232 line to supply + and - 12v on two the lines . The Develcon
unit draws its power from the control signal lines. If anyone has any input
on these two companies, or if anyone knows of other companies that make this
type of product, please contact me directly, or post your replies to the net.
					Thanks,
				Jim Wall  (sri-unix!fortune!wall)

Re: Modem eliminator

We recently acquired the International Data Sciences 6110 Modem Eliminator
based on a good experience with them at South Central Bell.  It works fine
as a Bell 208/209 replacement.  Draws its own AC power, switch selectable
speeds 1200-19.2k, and switch-selectable RTS/CTS delay of 0-200ms
(or will pass RTS/CTS through).  Cable lengths of 50 feet are advertised;
with good quality cable 500 feet is possible (we're using good 50' cable
with no problems, and SCB is using 200' cables).  $370 quantity one.

IDS is at 7 Wellington Rd, Lincoln RI 02865,  (401) 333-6200
