Table 3-39. Modem Port Options (3 of 4)

Disconnect Time (Minutes)

Possible Settings: 1 – 60

Default Setting: 10

Determines the amount of lapsed time before disconnecting a user session in minutes.

Display Conditions – This option only appears when:

￿Port Use is set to Terminal.

Inactivity Timeout is set to Enable.

1 – 60 – Sets the number of minutes allowed before the modem disconnects.

IP Address

Possible Settings: 001.000.000.000 – 223.255.255.255, Clear

Default Setting: Clear (000.000.000.000)

Specifies a unique IP address for accessing the system via the modem port. This option is only in effect when the modem port is configured as a network communication link.

Display Conditions – This option only appears when Port Use is set to Net Link.

001.000.000.000 – 223.255.255.255 – Shows the IP address for the modem port, which you can view or edit.

Clear – Clears the IP address for the modem port and fills the address with zeros (i.e., 000.000.000.000). When the IP Address is all zeros, the modem port uses the Node IP Address if one has been configured.

Subnet Mask

Possible Settings: 000.000.000.000 – 255.255.255.255, Clear

Default Setting: 000.000.000.000

Specifies the subnet mask needed to access the system. This option is only in effect when the modem port is configured as a network communication link.

Display Conditions – This option only appears when Port Use is set to Net Link.

000.000.000.000 – 255.255.255.255 – Shows the subnet mask for the modem port, which you can view or edit.

Clear – Clears the subnet mask for the COM port and fills the address with zeros. When the node subnet mask is all zeros, the IP protocol creates a default subnet mask based upon the class of the IP address: Class A: 255.000.000.000, Class B: 255.255.000.000, or Class C: 255.255.255.000.

Link Protocol

Possible Settings: PPP, SLIP

Default Setting: PPP

Specifies the link-layer protocol to be used. This option is only in effect when the modem port is configured as a network communication link.

Display Conditions – This option only appears when Port Use is set to Net Link.

PPP– Point-to-Point Protocol.

SLIP – Serial-Line Internet Protocol.
