There is even a package in the feed (digitemp) that can read them for you. You can have multiple sensors attached to the one serial adapter.
Is there a step-by-step guide available?

I have a usb-serial converter and DS1820 with RS232 adapter. The digitemp ipkg I found is only for DS2490, DS9097 and DS9097U.

I get the error:
USB ERROR: owAcquire called with invalid port string

Please help! What can I do?
