28.Os
29.Sh NAME
30.Nm umct
31.Nd Magic Control Technology USB-RS232 converter driver
32.Sh SYNOPSIS
33To compile this driver into the kernel,
34place the following lines in your
35kernel configuration file:
36.Bd -ragged -offset indent
37.Cd "device usb"
38.Cd "device ucom"
39.Cd "device umct"
40.Ed
41.Pp
42Alternatively, to load the driver as a
43module at boot time, place the following line in
44.Xr loader.conf 5 :
45.Bd -literal -offset indent
46umct_load="YES"
47.Ed
48.Sh DESCRIPTION
49The
50.Nm
51driver provides support for USB to RS-232 converters based on the Magic
52Control Technology USB-232 design.
53These devices support most of the
54standard RS-232 features including baud rates ranging from 300 to 115200
55bits per second.
56However, neither hardware nor software flow control
57seems to be supported.
58.Pp
59Access to devices under this driver is via the
60.Xr ucom 4
61framework and device nodes.
