# uticom(4)

Texas Instruments TUSB3410 USB serial adapter

## NAME

**uticom** – Texas Instruments TUSB3410 USB serial adapter

## SYNOPSIS

**uticom\* at uhub?** **ucom\*  at uticom?**

## DESCRIPTION

The **uticom** driver supports serial port functionality on devices based on the Texas Instruments TUSB3410 serial to USB converter chip.

The device is accessed through the [ucom(4)](/ucom/4.md) driver which makes it behave like a [tty(4)](/tty/4.md).

## SEE ALSO

[intro(4)](/intro/4.md), [tty(4)](/tty/4.md), [ucom(4)](/ucom/4.md), uhub(4), [usb(4)](/usb/4.md)

## HISTORY

The **uticom** device driver first appeared in OpenBSD 4.3.

## AUTHORS

The **uticom** driver was written by Dmitry Komissaroff ⟨*dxi@mail.ru*⟩ and Hasso Tepper ⟨*hasso@estpak.ee*⟩.

## CAVEATS

The **uticom** driver doesn't support devices that have an internal EEPROM with firmware, since such firmware is different to that supplied with OpenBSD.

Devices with multiple ports will attach all ports, though only the first port can be used for now.
