35 .Nd device driver for Cypress CY7C63743 and CY7C64013 USB to RS232 bridges
37 To compile this driver into the kernel,
38 place the following line in your
39 kernel configuration file:
40 .Bd -ragged -offset indent
44 Alternatively, to load the driver as a
45 module at boot time, place the following line in
47 .Bd -literal -offset indent
53 driver provides support for the Cypress CY7C63743 and CY7C64013 bridge
55 These chips were designed to provide a low-cost transition path to USB
56 for existing RS232 devices, and have fairly limited capabilities.
65 driver currently supports the following devices which incorporate
66 Cypress USB to RS232 bridge chips:
70 DeLorme Earthmate USB GPS receiver
