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 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 incorporate Cypress USB to RS232 bridge
       chips:

       •   DeLorme Earthmate USB GPS receiver
