5.2.4 Logging On Remotely
Normall a local network operator uses a VT-100 terminal to directly access the terminal
interface. But where central control or service access is required, the internal modem provides
an access method to the terminal interface from a remote location. The modem automatically
answers any incoming calls. The modem communicates at 2.4kbps using 8 data bits, one stop
bit and no parity.
To initiate a call, the remote operator dials in using a VT-100 compatible terminal. The remote
operator can press the <Enter> key to display the log-on screen. After entering a valid
password, the remote operator has complete access to the terminal interface.
To disconnect, the remote operator logs off and hangs up the line. The modem automatically
resests and waits for another call.
If an operator is logged on to the system with a local terminal when a modem call is received,
he will automatically be logged off the system and will not be able to restore local access until
the modem connections is broken.
