Usage Guidelines
The cont command typically is used when a user has interrupted the operation of the Cisco IOS software
by using the BREAK signal to enter ROM monitor mode, and then wants to continue with the original
Cisco IOS software image. This command can also be used to continue program execution when the user
uses the BREAK signal to interrupt the Cisco IOS software boot procedure, or has used the break
command to set a debug breakpoint.
Examples
In the following example, the cont command continues executing the Cisco IOS software image, after
the user has interrupted the software by sending a BREAK signal:
Router#
telnet> send brk
*** System received an abort due to Break Key ***
signal= 0x3, code= 0x0, context= 0x6208b290
PC = 0x606b5ab0, SP = 0x80007e00, RA = 0x606d2370
Cause Reg = 0xffffffff, Status Reg = 0x3400ff03
rommon 5 > cont
Router#
OL-1581-07
cont [address]
(Optional) Specifies the address in memory at which the router should continue
execution. If address is not specified, the command continues execution at the
address currently stored in the program counter (PC) register.
Caution
Do not use the address option unless instructed to do so by Cisco TAC
engineers.
