ACM Driver of USB Communication Device Class

This driver enhancement is new in the Developer 5/07 release.

Starting with this release, the usbsacm driver supports USB modems that conform to the specification for the Universal Serial Bus Communication Device Class Abstract Control Model (USB CDC ACM). You can attach the usbsacm driver with your mobile phone, PCMCIA cards, or any modem-like devices. The usbsacm driver generates term nodes under /dev/term/. You can then use pppd(1M) to transmit datagrams over these serial ports.
