Auto-dial capability This feature is required when the modem is used for outbound modem pooling. It allows the modem to go off-hook and dial the remote number (such as Smartmodem Hayes-2400 or Bizcomp).

Auto-reset capability This feature is required when the modem is used for outbound modem pooling. The modem should execute auto-reset when the DTR lead goes OFF. As a result, the modem must reset all its internal parameters to the default values. This feature prevents the users of the modem pool from modifying the modem’s default parameters to inappropriate values.
