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

	     device usb
	     device ucom
	     device uchcom

       Alternatively, to load the driver as a module at	boot time,  place  the
       following line in loader.conf(5):

DESCRIPTION
       The uchcom driver provides support for the WinChipHead CH341/CH340 USB-
       to-RS-232 Bridge	chip.

       The device is accessed through the ucom(4) driver which makes it	behave
       like a tty(4).

HARDWARE
       The uchcom driver supports the following	adapters:

       •   HL USB-RS232

FILES
       /dev/ttyU*	for callin ports
       /dev/ttyU*.init
       /dev/ttyU*.lock	corresponding  callin initial-state and	lock-state de-
			vices

       /dev/cuaU*	for callout ports
       /dev/cuaU*.init
       /dev/cuaU*.lock	corresponding callout initial-state and	lock-state de-

HISTORY
       The uchcom driver first appeared	in NetBSD.  The	first FreeBSD  release
       to include it was FreeBSD 8.0.

BUGS

       stop bit	line.
