NAME

umct – Magic Control Technology USB-RS232 converter driver

CONTENTS

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:

FILES

/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

SEE ALSO

tty(4), ucom(4), usb(4)

HISTORY

AUTHORS

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