console port) try rtty. It's old, and it hasn't been updated in ages,

If the OpenBSD host is located in the same physical site as the Cisco
products, you have the additional option of providing serial console
access to the console port on the Cisco devices through the OpenBSD
bastion host. To take this a step further, you can log all serial
