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

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