umct — Magic Control Technology USB-RS232 converter driver

       The umct driver was written by Scott Long <scottl@FreeBSD.org>.

Debian                                           April 26, 2017                                          UMCT(4)

       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.

/dev/ttyU*       for callin ports
       /dev/ttyU*.init/dev/ttyU*.lock  corresponding callin initial-state and lock-state devices

       /dev/cuaU*       for callout ports
       /dev/cuaU*.init/dev/cuaU*.lock  corresponding callout initial-state and lock-state devices

       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

       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>.
