Port Monitor Administrative File

A port monitor's current directory contains an administrative file named _pmtab. _pmtab is maintained by the pmadm command in conjunction with a port monitor-specific administrative command.

The port monitor administrative command for a listen port monitor is nlsadmin(); the port monitor administrative command for ttymon is ttyadm(). Any port monitor written by a user must be provided with an administrative command specific to that port monitor to perform similar functions.
