A standard modem remains silent and waits for the answering modem to send a carrier. However, most Hayes-compatible modems can be handed a command such as 'ATDT5551234R', and they will dial, then go into answer mode and _send_ a carrier. The box to which you refer apparantly routes incoming carrier tone to the modem. This would work fine for private use, but wouldn't be satisfactory for a BBS. (Too hard to get users to use non-standard techniques.) Roy M. Silvernail now available at: cybrspc!roy@cs.umn.edu
