The ttymon administrative file is updated by the sacadm and pmadm commands, as well as by the ttyadm command. The ttyadm command formats ttymon-specific information and writes it to standard output, providing a means for presenting formatted ttymon-specific data to the sacadm and pmadm commands.
Thus, the ttyadm command does not administer ttymon directly. The ttyadm command complements the generic administrative commands, sacadm and pmadm. For more information, see the ttyadm(1M) man page.
