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
