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.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 programs such as tip(1) or pppd(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.
BUGS
Prior to FreeBSD 6.0 ucom created /dev/ucom? rather than the uniform
device names created today. Old scripts must be adjusted accordingly.
FILES
/dev/cuaU?
/dev/ttyU?

HISTORY
