UCYCOM(4)		    Kernel Interfaces Manual		     UCYCOM(4)

NAME
       ucycom  --  device  driver  for	Cypress	CY7C63743 and CY7C64013	USB to
       RS232 bridges

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

	     device usb
	     device hid
	     device ucom
	     device ucycom

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

	     ucycom_load="YES"

DESCRIPTION
       The ucycom driver  provides  support  for  the  Cypress	CY7C63743  and
       CY7C64013  bridge  chips.   These chips were designed to	provide	a low-
       cost transition path to USB for existing	RS232 devices, and have	fairly
       limited capabilities.

       The ucycom driver behaves like a	tty(4).

HARDWARE
       The ucycom driver currently supports the	following devices which	incor-
       porate Cypress USB to RS232 bridge chips:

       •   DeLorme Earthmate USB GPS receiver

       /dev/ttyU*	for callin ports
       /dev/ttyU*.init

			vices

       /dev/cuaU*	for callout ports
       /dev/cuaU*.init
