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

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

SEE ALSO

     tty(4), usb(4)

HISTORY

     The ucycom driver first appeared in FreeBSD 5.3.
