Circuit Card Description and Installation
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.
