NAME

ucom - USB tty support

SYNOPSIS

To compile this driver into the kernel, place the following line in your kernel configuration file:

device ucom

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:

ucom_load="YES"

DESCRIPTION

The ifconfig driver attaches to USB modems, serial ports, and other devices that need to look like a tty. The ifconfig driver shows a behavior like a tty(4). This means that normal programs such as tip(1) or ppp(8) can be used to access the device.

The portno locater can be used to decide which port to use for devices that have multiple external ports.

FILES

/dev/cuaU?

/dev/ttyU?

HISTORY

The ifconfig driver was adopted from Nx in March of 2002. This manual page was adopted from Nx by An Tom Rhodes Aq trhodes@FreeBSD.org in April 2002.

BUGS

Prior to Fx 6.0 ifconfig created /dev/ucom? rather than the uniform device names created today. Old scripts must be adjusted accordingly.
