NAMEumodem - USB modem support
SYNOPSISTo compile this driver into the kernel, place the following lines in your kernel configuration file: device umodem device ucom Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): umodem_load="YES"
DESCRIPTIONThe umodem driver provides support for USB modems in the Communication Device Class using the Abstract Control Model. These modems are basically standard serial line modems, but they are accessed via USB instead. They support a regular AT command set. The commands can either be multiplexed with the data stream or handled through separate pipes. In the latter 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).
HARDWAREDevices supported by the umodem driver include: +
SEE ALSOtty(4), ucom(4), usb(4)
HISTORYThe umodem driver appeared in NetBSD 1.5. This manual page was adopted from NetBSD by Tom Rhodes <trhodes@FreeBSD.org> in April 2002.
BUGSOnly modems with multiplexed commands and data are supported at the moment. UMODEM(4)
