Table 3-38. Communication Port Options (1 of 5)

Port Use
Possible Settings: Terminal, Net Link, Modem PassThru
Default Setting: Termin al
Assigns a specific use to the COM port.
NOTE: If the Default IP Destination is set to COM (see Table3-31, Node IP Options)
and you change Port Use to Terminal, the Default IP Destination is forced to None.
Termi nal – The COM port is used for the asynchronous terminal connection.
Net Link – The COM port is the network communications link to the IP network or IP
device port. You cannot change Port Use to Net Link when the Modem PassThru feature
is enabled. When you try, the Cannot change Port Use – Modem PassThru is
enabled message is displayed.
Modem PassThru – Available to the FrameSaver SLV 9626 only, the COM port is
connected to the router’s auxiliary (AUX) or console port so the router can be accessed
via a dial-up connection to the unit. When this feature is active, a logical connection
between the unit’s modem and COM ports is made, and data received over the modem
port is transmitted out the COM port to the router’s AUX or console port. When an escape
sequence (minus, minus, minus, with a minimum of 50 ms between each) is detected, the
FrameSaver unit switches back to normal us er interface operation.
Data Rate (Kbps)
Possible Settings: 9.6, 14.4, 19.2, 28.8, 38.4, 57.6, 115.2
Default Setting: 19.2
Specifies the rate for the COM port in kilobits per second.
9.6 – 115.2 Kbps – Sets the communication port speed.
Character Length
Possible Settings: 7, 8
Default Setting: 8
Specifies the number of bits needed to represent one character.
NOTE: Character length defaults to 8 and cannot be changed if Port Use is set to Net
Link.
7 – Sets the character length to seven bits.
8 – Sets the character length to eight bits. Use this setting if using the COM port as the
network communication link.
