I don\'t know of a PPP client for OZ that will edit these scripts for you, so you may need to edit the scripts manually. This links should point you in the right direction:
http://www.openzaurus.org/oz_website/faq/faq?id=76Since you will not be using IR and your modem is probably on serial 1 by default, look at the line:
user \'username\' /dev/ircomm 115200 -detach
I think should be changed to something like:
user \'username\' /dev/ttyS1 115200 -detach
For serial 2 it would be:
user \'username\' /dev/ttyS2 115200 -detach
I am not 100% this will work since I don\'t use dial-up modems generally and have not tested it, but it is a place for you to get started.
