UMODEM(4) Kernel Interfaces Manual UMODEM(4) NAME umodem -- USB Communication Device Class serial (CDC ACM) driver SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: device usb device ucom device umodem Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): umodem_load="YES" DESCRIPTION The umodem driver provides support for USB modems and serial devices that implement the Communication Device Class Abstract Control Model (CDC ACM). It also provides device-side CDC ACM support. Supported modems are basi- cally standard serial line modems, but they are accessed via USB instead. They support a regular AT command set. The commands can either be multi- plexed with the data stream or handled through separate pipes. In the lat- ter case the AT commands have to be given on a device separate from the data device. The device is accessed through the ucom(4) driver which makes it behave like a tty(4). HARDWARE Devices supported by the umodem driver include: * 3Com 5605 * Curitel PC5740 Wireless Modem * Kyocera AH-K3001V Mobile Phone(WILLCOM) * Kyocera WX320K Mobile Phone(WILLCOM) * Metricom Ricochet GS USB wireless modem * Sierra MC5720 Wireless Modem * Yamaha Broadband Wireless Router RTW65b * ELSA MicroLink 56k USB modem * Sony Ericsson W810i phone * Sonim XP5300 Force FILES /dev/ttyU* for callin ports /dev/ttyU*.init /dev/ttyU*.lock corresponding callin initial-state and lock-state devices /dev/cuaU* for callout ports /dev/cuaU*.init /dev/cuaU*.lock corresponding callout initial-state and lock-state devices SEE ALSO tty(4), ucom(4), usb(4) HISTORY The umodem driver appeared in NetBSD 1.5. This manual page was adopted from NetBSD by Tom Rhodes <trhodes@FreeBSD.org> in April 2002. BUGS Only modems with multiplexed commands and data are supported at the moment.
