pmchat
The
pmchat
command acts similarly to the standard
chat
command, but all serial port access is
directed via the portmanager.
Example:
To run a chat script
via
the portmanager:
# pmchat -v -f /etc/config/scripts/port08.chat < /dev/port08
For more information on using
chat
(and
pmchat
), you should consult the UNIX man pages:

bin/getdoc.cgi?coll=linux&db=man&fname=/usr/share/catman/man8/chat.8.html
pmusers
The
pmusers
command is used to query the portmanager for active user sessions.
Example:
To detect which users are currently active on which serial ports:
# pmusers
This command will not output anything if there are no active users currently connected to any
ports, otherwise, it will respond with a sorted list of usernames per active port:
Port 1:
user1
user2
Port
2:
user1
Port
8:
user2
The above output indicates that a user named “
user1
” is actively connected to ports 1 and 2,
while “
user2
” is connected to both ports 1 and 8.
