I bought this Connectland usb/serial connector to configure my Cisco routers. Since now I’m using Ubuntu, this Linux just picks up the connector.
[4309733.840000] usb 2-2: new full speed USB device using uhci_hcd and address 5
[4309733.936000] pl2303 2-2:1.0: PL-2303 converter detected
[4309733.940000] usb 2-2: PL-2303 converter now attached to ttyUSB0
Then I installed minicom.
$ sudo apt-get install minicom
Run the minicom program and using command CTRL-a z o (inside minicom) to configure the minicom serial port. Make sure the configuration look like this.
A - Serial Device : /dev/ttyUSB0
B - Lockfile Location : /var/lock
C - Callin Program :
D - Callout Program :
E - Bps/Par/Bits : 9600 8N1
F - Hardware Flow Control : Yes
G - Software Flow Control : No
Save the configuration with whatever name you want. In this case is “cisco”.
Next time you want to configure your router using minicom, just type “minicom cisco”
