Suggest they find a converter that is supported in Linux or find a computer with a real serial port. These look like some great links though on the process.

Hi Clint Tinsley!

If I hear you then the Cisco routers have a serial connection
(probably 9 pin RS232) which they connect to a serial to USB adapter
which is then connected to a computer without a serial connector?  Do
I hear you???

If you really cannot get the USB-Serial adapters to work (probably
worth a bit of time) then perhaps something like this would help:

You could probably obtain one at a used computer shop for a song.

Another direction is serial to NIC:

How about the printer port?

Good Hunting!
