In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
This is a driver for Digi International's Neo and Classic series
of cards which provide multiple serial ports. You would need
something like this to connect more than two modems to your Linux
box, for instance in order to become a dial-in server. This driver
supports PCI boards only.

If you have a card like this, say Y here, otherwise say N.

To compile this driver as a module, choose M here: the
module will be called jsm.
