Send a string to the com port?

Anyone have any idea how I could send a string of hex to the serial / com port?
Have tried launch file, launching a DOS batch file with something like MODE COM2: BAUD=96 PARITY=N DATA=8 STOP=1 ECHO “B3000FF” >COM2. but there must be a better way?

Help :?:

In the latest version of Opus, you may copy a file to the com port (destination: "com1:"). The file contains the string you want to send. This works very well.
In older versions I used an external utility to be launched by Opus. A parameter determined the string that was send out. Problem was that the utility had to open and close the port each time, which made it impossible to send strings in short time intervals. For some reason, after having send many strings, Windows refused to close the port, thus blocking further sends. So I am happy with the file copy feature: it does not show (works in the background) and simply cues up strings to be send if time intervals are to short.
