USB to Serial Console Connectivity with Kermit (Mac OS X)

This solutions covers utilizing a USB to Serial Dongle with Kermit (within Mac OS X) for console connectivity to any device (in this case a Cisco Router). This solution can be duplicated for devices requiring different line speed, flow control or parity settings with ‘Kerbang’ scripts. It is a simple solution and has helped me in many situations. Check out what I would do:

Have you ever found yourself troubleshooting a voice issue and you come to the point of needing to grab a packet capture on a router? This solution has caused me to push all of my router build’s of material to have high capacity flash cards (without compromising cost of course) and in those instances where I need more space than alloted in flash I cary a 1GB Compact Flash Card temporarily to grab these captures. I have found this a great tool when needing to troubleshoot:

SIP Trunks through CUBE for detecting bleeding DTMF
Multicast Music on Hold to the ISR then out via a PRI Trunk
Audio quality issues through an ISR
