UXRCOM(4) FreeBSD Kernel Interfaces Manual UXRCOM(4)
NAME
uxrcom - Exar XR21V141x USB serial adapter
SYNOPSIS
uxrcom* at uhub?
ucom* at uxrcom?
HARDWARE
The uxrcom driver supports serial adapters based on the XR21V1410,
XR21V1412, and XR21V1414 chipsets. Devices range from single port to
eight port (implemented as a USB hub and two uxrcom four port instances
behind it). Examples of hardware known to work with this driver are:
Gearmo GM-U28RS232 8 Port USB to Serial DB9 RS232 Adapter
DESCRIPTION
The uxrcom driver attaches the Exar XR21V141x multiport chipset with
individual port drivers via ucom(4), which makes it behave like a tty(4).

on the OpenBSD driver but uses the common umodem(4) framework. The
NetBSD driver was written by by Simon Burge <
