NAME
     uchcom -- USB support for WinChipHead CH341/CH340 serial adapters driver

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

	   device uchcom
	   device ucom

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

	   uchcom_load="YES"

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).

SEE ALSO
     tty(4), ucom(4), usb(4)

HISTORY
     The uchcom driver appeared in NetBSD 5.0 and was imported into
     DragonFly 1.11.

BUGS
     Actually, this chip seems unable to drive other than 8 data bits and 1
     stop bit line.
