34.Sh NAME
35.Nm uticom
36.Nd Texas Instruments TUSB3410 RS232 to USB converter
37.Sh SYNOPSIS
38To compile this driver into the kernel,
39place the following lines in your
40kernel configuration file:
41.Bd -ragged -offset indent
42.Cd "device uticom"
43.Cd "device ucom"
44.Ed
45.Pp
46Alternatively, to load the driver as a
47module at boot time, place the following line in
48.Xr loader.conf 5 :
49.Bd -literal -offset indent
50uticom_load="YES"
51.Ed
52.Sh DESCRIPTION
53The
54.Nm
55driver supports virtual serial port functionality on devices based on Texas
56Instruments TUSB3410 serial to USB converter chip. Note that the driver
57doesn't support devices which have internal EEPROM with firmware.
58.Pp
59The device is accessed through the
60.Xr ucom 4
61driver which makes it behave like a
62.Xr tty 4 .
63.Sh SYSCTL
64.Bl -tag -width indent
65.It Va hw.usb.uticom.stickdsr
66If set to non-zero, DSR (Data Set Ready) signal from DCE is ignored and the
67TIOCM_DSR state flag is set unconditionally. It can be used if DSR signal
68from DCE is unreliable. Default is 0.
