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

       The ucycom driver and this manual page were written by Dag-Erling Smørgrav <des@FreeBSD.org>.

Debian                                           April 26, 2017                                        UCYCOM(4)

       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).

/dev/ttyU*       for callin ports
       /dev/ttyU*.init/dev/ttyU*.lock  corresponding callin initial-state and lock-state devices

       /dev/cuaU*       for callout ports
       /dev/cuaU*.init/dev/cuaU*.lock  corresponding callout initial-state and lock-state devices

       The  ucycom driver currently supports the following devices which incorporate Cypress USB to RS232 bridge
       chips:

       •   DeLorme Earthmate USB GPS receiver

       The ucycom driver first appeared in FreeBSD 5.3.
