# uvscom(4)

USB support for SUNTAC Slipper U VS-10U serial adapters driver

## NAME

**uvscom** – USB support for SUNTAC Slipper U VS-10U serial adapters driver

To compile this driver into the kernel, place the following lines in your kernel configuration file:

**device usb** **device ucom** **device uvscom**

Alternatively, to load the driver as a module at boot time, place the following line in [loader.conf(5)](/loader.conf/5.md):

```

```

The **uvscom** driver supports the following adapters:

- DDI Pocket Air H" C@rd

- DDI Pocket Air H" C@rd 64

## DESCRIPTION

The **uvscom** driver provides support for the SUNTAC Slipper U VS-10U chip. Slipper U is a PC Card to USB converter for data communication card adapters.

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