|
|
.Nd device driver for Cypress CY7C63743 and CY7C64013 USB to RS232 bridges
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following line in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device usb"
|
|
.Cd "device ucom"
|
|
.Cd "device ucycom"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
ucycom_load="YES"

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver behaves like a
|
|
.Xr tty 4 .
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
