AppendixB Configuration Register Information for the CiscouBR10012 Universal Broadband Router

Configuration Bit Meanings

Bit 8

Bit 8 controls the console Break key. Setting bit 8 (the factory default) causes the processor to ignore

the console Break key. Clearing bit 8 causes the processor to interpret Break as a command to force the

system into the bootstrap monitor, halting normal operation. A Break can be sent in the first sixty

seconds while the system reboots, regardless of the configuration settings.

Bit 10 and Bit 14

Bit 10 controls the host portion of the Internet IP broadcast address. Setting bit 10 causes the processor

to use all zeros; clearing bit 10 (the factory default) causes the processor to use all ones. B it 10 interacts

with bit 14, which controls the network and subnet portions of the IP broadcast address. TableB-4 shows

the combined effect of bit 10 and bit 14.

Note The console line rate on Cisco universal broadband routers is fixed at 9600 and cannot be changed. For

additional information about configuring baud rates, refer to oneor more of these documents on

Bit 11 and Bit 12

Bit 11 and Bit 12 in the configuration register determine the baud rate of the console terminal. TableB-5

shows the bit settings for the four available baud rates. (The factory set default baud rate is 9600.)
