USB to serial adapter

USB to serial adaptors allow you to use RS232 based hardware via a computer's USB port.

I bought SiteCom's USB to serial cable and it works perfect with Linux:

• open a console
• attach the adaptor
• read the syslog using the command

dmesg

• in the syslog you will find some lines reading like
