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).

AUTHORS
The uxrcom driver for the single port XR21V1410 was written by Mark Kettenis <kettenis@openbsd.org>. The multi-port NetBSD driver is based on the OpenBSD driver but uses the common umodem(4) framework. The NetBSD driver was written by by Simon Burge <simonb@netbsd.org>.
