.Sh NAME
.Nm uticom
.Nd Texas Instruments TUSB3410 RS232 to USB converter
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device uticom"
.Cd "device ucom"
.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
uticom_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver supports virtual serial port functionality on devices based on Texas
Instruments TUSB3410 serial to USB converter chip. Note that the driver
doesn't support devices which have internal EEPROM with firmware.
.Pp
The device is accessed through the
.Xr ucom 4
driver which makes it behave like a
.Xr tty 4 .
.Sh SYSCTL
.Bl -tag -width indent
.It Va hw.usb.uticom.stickdsr
If set to non-zero, DSR (Data Set Ready) signal from DCE is ignored and the
TIOCM_DSR state flag is set unconditionally.  It can be used if DSR signal
from DCE is unreliable.  Default is 0.
