Example:
To detect which users are currently active on which serial ports:
    # pmusers
This command will output nothing 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 con-
nected to ports 1 and 2, while “user2” is connected to both ports 1 and 8.
