[net.dcom] 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,
