HWIC-8A Base Config

Normally they are to expensive for what they do, but the other day I found a HWIC-8A from ebay at a good price. As a result, I now have remote Serial & JTAG access to a bunch of test equipment via my Cisco Router. The following is a quick sample config I tossed together on how to configure it.

If needed the following is the pin-out to the Cisco Octal Cable: http://www.cisco.com/c/en/us/support/docs/dial-access/asynchronous-connections/14958-24.html

! Create a AAA authentication policy that will
! not make the user supply local credentials to
! connect to the Async TTY's.

aaa authentication login TERMSERV none

! Create an ACL to control who can connect.
! Warning: Anyone will be able to connect to the
! tty's when transport is configured.
