Basic Configuration
5.8. Serial Port Configuration
The Serial Port Configuration menus allow you to select parameters for the VMR/NPS
Setup Port. The Setup Port (Port 1) can be configured for connection to a local PC or
Modem. In addition, the Serial Port Configuration menu (Port Parameters) can also be
used to set communications parameters, disable Administrator level commands at the
Setup Port and also select a number of other Setup Port Parameters described below..
The Setup Port Configuration menu allows the following parameters to be defined:
CommunicationSettings:
• BaudRate: Any standard rate from 300 bps to 115.2K bps. (Default = 9600 bps)
• Bits/Parity: (Default = 8-None).
• StopBits: (Default = 1).
• HandshakeMode: XON/XOFF, RTS/CTS (hardware), Both, or None.
(Default = RTS/CTS).
GeneralParameters:
• AdministratorMode: Permits/denies port access to Administrator and
SuperUser level accounts. When enabled (Permit), the port will be allowed to
invoke Administrator and SuperUser level commands, providing they are issued
by an account that permits them. If disabled (Deny), then accounts that permit
Administrator and SuperUser level commands will not be allowed to access
command mode via this port. (Default = Permit).
• LogoffCharacter: The Logoff Character determines the command(s) or
character(s) that must be issued at this port in order to disconnect this port from
another port. Note that the Logoff Character does not apply to Direct Connections.
(Default = ^X.)
• SequenceDisconnect: Enables/Disables and configures the disconnect
command. This item offers the option to disable the Sequence Disconnect, select a
one character format or a three character format. (Default = One Character.)
• InactivityTimeout: Enables and selects the Timeout Period for this port. If
enabled, the Setup Port will disconnect when no additional data activity is detected
for the duration of the timeout period. (Default = 5 Minutes.)
• CommandEcho: Enables or Disables command echo at the Setup Port. When
disabled, commands that are sent to the Setup Port will still be invoked, but the
actual keystrokes will not be displayed on your monitor. (Default = On.)
• AcceptBreak: Determines whether the port will accept breaks received from the
attached device. When enabled, breaks received at the port will be passed to any
port that this port is connected to. When disabled, breaks will be refused at this
port. (Default = On.)
