linmodem

[Ed Kapitein]

Hi all,

I recently bought another freerunner and i have a "plan" with my
provider that will give me free calls between my family members.

Is there someone who ever hookup up two freerunners, using phonecalls?
I took a look at [1] that uses a linmodem, software only modem.
With this software you can hook up two computers using the soundcards.
Is Something simmilar possible wit 2 FR 's? 

Kind regards,
Ed
