NAME

     umct — Magic Control Technology USB-RS232 converter driver

SYNOPSIS

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

           device usb
           device ucom
           device umct

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

           umct_load="YES"

DESCRIPTION

     The umct driver provides support for USB to RS-232 converters based on the Magic Control
     Technology USB-232 design.  These devices support most of the standard RS-232 features
     including baud rates ranging from 300 to 115200 bits per second.  However, neither hardware
     nor software flow control seems to be supported.

     Access to devices under this driver is via the ucom(4) framework and device nodes.

HARDWARE

     The umct driver supports the following adapters:

     •   Belkin F5U109
     •   Belkin F5U409
     •   D-Link DU-H3SP USB BAY Hub
     •   Magic Control Technology USB-232
     •   Sitecom USB-232

HISTORY

     The umct driver appeared in FreeBSD 5.2.  It is loosely based on the ubsa(4) driver by
     Alexander Kabaev <kan@FreeBSD.org> with documentation from Wolfgang Grandeggar
     <wolfgang@cec.ch>.
