The SCS holds DTR low until it forms a valid network session. The attached device can
then monitor the SCS DTR output by tying it to its CD input. In addition, the SCS has
DSRLogout enabled, so if the attached device drops its DTR, the network connection
terminates, and the serial port logs out.
Remote User Dial-Up
You can accomplish dial-up access to the SCS either using a data-link protocol, typically
PPP, or using an ASCII-based terminal connection with a terminal emulation application
such as HyperTerminal.
Connectivity to the SCS from a remote location requires that you create a user account,
connect and configure a modem, enable authentication, and specify an IP address range
for use during remote sessions.
To configure your SCS for remote user dial-up:
1. Create a user account.
a) From the Quick Setup column on the left, select Users.
b) Enter the user name and click Create.
c) Click the Configure link next to the user name.
d) Enter a password in the Password field.
e) For a PPP connection, type set PPP in the Login Command field.
f) For a terminal emulation connection to the console menu, enter menu in the
Login Command field.
g) For a terminal emulation connection to the local SCS prompt, leave the Login
Command field blank.
h) Click the Update button.
