UCHCOM(4)						   BSD Kernel Interfaces Manual 						 UCHCOM(4)

NAME

     uchcom -- WinChipHead CH341/CH340 serial adapter 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).

HARDWARE

     The uchcom driver supports the following adapters:

     o	 HL USB-RS232

SEE ALSO

     tty(4), ucom(4), usb(4)

HISTORY

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

BUGS

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