.Nm umct
|
|
.Nd Magic Control Technology USB-RS232 converter driver
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device usb"
|
|
.Cd "device ucom"
|
|
.Cd "device umct"
|
|
.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
|
|
umct_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for USB to RS-232 converters based on the Magic
|
|
Control Technology USB-232 design.
|
|
These devices support most of the
|
|
standard RS-232 features including baud rates ranging from 300 to 115200
|
|
bits per second.
|
|
However, neither hardware nor software flow control
|
|
seems to be supported.
|
|
.Pp
|
|
Access to devices under this driver is via the
|
|
.Xr ucom 4
|
|
framework and device nodes.
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver supports the following adapters:
