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