33 .Nd device driver for Cypress CY7C63743 and CY7C64013 USB to RS232 bridges
35 To compile this driver into the kernel,
36 place the following line in your
37 kernel configuration file:
38 .Bd -ragged -offset indent
45 Alternatively, to load the driver as a
46 module at boot time, place the following line in
48 .Bd -literal -offset indent
54 driver provides support for the Cypress CY7C63743 and CY7C64013 bridge
56 These chips were designed to provide a low-cost transition path to USB
57 for existing RS232 devices, and have fairly limited capabilities.
66 driver currently supports the following devices which incorporate
67 Cypress USB to RS232 bridge chips:
71 DeLorme Earthmate USB GPS receiver
74 .Bl -tag -width "/dev/ttyU*.init" -compact
77 .It Pa /dev/ttyU*.init
78 .It Pa /dev/ttyU*.lock
79 corresponding callin initial-state and lock-state devices
83 .It Pa /dev/cuaU*.init
84 .It Pa /dev/cuaU*.lock
85 corresponding callout initial-state and lock-state devices
94 driver first appeared in
100 driver and this manual page were written by
