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

       /dev/cuaU*       for callout ports
