Default sequence 5 is:
D2A20’ Connection Password:’ P2 ’^M^J’Z
%I
n;ppppp;sssssEdit Connection Security Password
(V.25bis Synchronous Mode)
Edit Connection Security password n, where n = 0 to 49, ppppp is the Security
Database Password, and sssss is the Connection Security Password.
Allows the security administrator to set a new password or change the existing
password. If you set $M1 or $M2, the modem verifies passwords set by this command
during connection establishment.
You can password-protect the Connection Security password with the $P command. If
a Security Database Password exists, you must enter it accurately for the new
Connection Security Password to take effect. If there is no Security Database
Password, you can just enter the two semicolons and new Connection Security
Password.
Passwords must contain exactly five alphanumeric characters. The modem ignores
upper case or lower case and parity.
You can enter up to fifty passwords for both the originating and answering modems
(see %In, where n = 0 to 49). During connection establishment, the originating modem
sends password 0 to the answering modem. The answering modem checks its list of
passwords to see whether the password matches any of passwords 0 to 49. If there is a
match, the connection proceeds. If not, the connection fails.
Where:
Means:
D2A20 ’Connection
Password:’P2
send the string Connection Password: to the remote user
and wait for a string containing the user’s password. Echo
periods to the remote user. If a string is not received within
20 seconds, abort and disconnect.
'^M^J'
send a carriage return and a line feed.
Z
check the Connection Security Password Database for the
password. If there is a match, the connection proceeds. If
no match, retry the sequence up to two times more (for a
total of three tries), then disconnect.
