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  capabili-
     ties.

     The ucycom driver behaves like a tty(4).

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

     *	 DeLorme Earthmate USB GPS receiver
