41.Dt UFTDI 4
42.Os
43.Sh NAME
44.Nm uftdi
45.Nd USB support for serial devices based on the FTDI chips
46.Sh SYNOPSIS
47To compile this driver into the kernel,
48place the following lines in your
49kernel configuration file:
50.Bd -ragged -offset indent
51.Cd "device uftdi"
52.Cd "device ucom"
53.Ed
54.Pp
55Alternatively, to load the driver as a
56module at boot time, place the following line in
57.Xr loader.conf 5 :
58.Bd -literal -offset indent
59uftdi_load="YES"
60.Ed
61.Sh DESCRIPTION
62The
63.Nm
64driver provides support for RS-232 (and possibly RS-485) virtual COM
65port functionality in various FTDI chips:
66.Pp
67.Bl -dash -compact -offset indent
68.It
69FT8U100AX multi-function hub controller chip
70.It
71FT8U232AM USB UART chip
72.It
73FT232 series USB UART chips
74.It
75FT2232 series dual USB UART/FIFO chips
76.El
77.Pp
78The
79.Nm
80driver doesn't support any other serial protocol supported by these chips.
81These protocols might be supported by libftdi userspace library.
82.Pp
83The device is accessed through the
84.Xr ucom 4
85driver which makes it behave like a
86.Xr tty 4 .
