I'm looking for a modem pair with some (to my understanding) fairly unusual qualities; I recall hearing that these may be available but am not sure where to start looking. I am looking at connecting two sites that are in line of sight. I'd like to get a nice high speed connection, and it occurs to me that a modem pair using IR lasers as the tranfser would handle the problem nicely. Anyone have any recommendations? Any ideas where to start looking? And, as long as I'm in the area, how about serial muxes on this line, I'd like to TCP/IP using a SLIP on the line but a short term solution might be to mux the connections. Current plans suggest a maximum 76K baud max burst so a 38K line muxed would handle the problem nicely. I think a solution using a real high speed connection (say T3) would be overkill and that anything less than 19K baud would be too slow. Ideas? -- Russ Kepler - Basis Int'l SNAIL: 5901 Jefferson NE, Albuquerque, NM 87109 UUCP: bbx.basis.com!russ PHONE: 505-345-5232

Last I checked, in the NY area, the price was $70 per month on both sides plus $5 per mile between the sites as the crow flies per month. I think the services is called DDS 2. Another alternative is to get a couple V.32 bis modems. They go at a minimum of 1600 chars/sec and get over 3000 chars/sec sending compressible data. ------------------------------------------------------------------------------ | Jacob M.
