Drop any linux or assembly bits, you should not need them.

cfmakeraw() is useful API, makes sure you don't have a terminal discipline enabled on the port....

otherwise, just make sure you set the baud rate, characters bits, parity and stop, and set the file descriptor to blocking or nonblocking as per your whim.

umct

UMCT(4) 						   BSD Kernel Interfaces Manual 						   UMCT(4)

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 umct
	   device ucom

     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:

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

SEE ALSO

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

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>.

AUTHORS

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