31.Sh NAME
32.Nm ucycom
33.Nd device driver for Cypress CY7C63743 and CY7C64013 USB to RS232 bridges
34.Sh SYNOPSIS
35To compile this driver into the kernel,
36place the following line in your
37kernel configuration file:
38.Bd -ragged -offset indent
39.Cd "device usb"
40.Cd "device hid"
41.Cd "device ucom"
42.Cd "device ucycom"
43.Ed
44.Pp
45Alternatively, to load the driver as a
46module at boot time, place the following line in
47.Xr loader.conf 5 :
48.Bd -literal -offset indent
49ucycom_load="YES"
50.Ed
51.Sh DESCRIPTION
52The
53.Nm
54driver provides support for the Cypress CY7C63743 and CY7C64013 bridge
55chips.
56These chips were designed to provide a low-cost transition path to USB
57for existing RS232 devices, and have fairly limited capabilities.
