  1. /* GPRS-PPP.C Here is a quick sample of the GPRS - PPP connection procedure: For standard GPRS connections use yourAPN = internet ( vodafone ) and with blank username and password use if ((pppcom = _open("ppp:" PPPCOM, _O_RDWR | _O_BINARY)) == -1) instead of if ((pppcom = _open("ppp:" PPPCOM "/" PPPUSER "/" PPPPASS, _O_RDWR |_O_BINARY)) == -1) For the function "WebServer" you can cut and paste httpserv.c from: * * Register our device for the file system. */ NutRegisterDevice(&devUrom, 0, 0); onwards.
