NAME

ucom — USB tty support

SYNOPSIS

To compile this driver into the kernel, place the following line in your kernel configura‐ tion file: device ucom Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): ucom_load="YES"

DESCRIPTION

The ucom driver attaches to USB modems, serial ports, and other devices that need to look like a tty. The ucom driver shows a behavior like a tty(4). This means that normal pro‐ grams 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 ucom driver was adopted from NetBSD in March of 2002. This manual page was adopted from NetBSD by Tom Rhodes <@FreeBSD.org> in April 2002.

BUGS

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