Debug features
When the Nortel Call Recording Card starts, the 8051 auxiliary processor
controls the serial port and uses it to provide debug information, progress of
self tests, and so on. After the 8051 auxiliary processor releases the main
processor (ixp1200) from reset, the main processor (by default) grants
VxWorks shell access through this port. The card also supports remote
access to the shell through telnet.
