Matlab, comdlg32.ocx, MSCOMM32.OCX (need help pleas)

Okay, so, I would like to communicate via RS232 some ascii code. But to open the port, it seems that I don't have all the informations on HOW To. fwrite, fprintf doesn't work properly, maybe because the set of the communication protocole is not good (baudrate, stopbits etc..)

But I have a program, that work, but for only one purpose, I want to do the same thing, but with matlab. I try to decompile it, but it's uncomprehensible. So I have found Two files, comdlg32.ocx, MSCOMM32.OCX, in the program file (that work).

What I would like to do, is to call them, in matlab, to set the communication protocole instead of : s= 'com1', set.Baudrate etc...

Is it possible ?

PS : I cannot decompile those files, but it seems that they have been change for the program that work. (maybe I can use them with my matlab program)

Best regards

How can I use MSComm.ocx from windows, to set my rs232 communication protocol ?

Best regards

(I tried fprintf, fwrite, with many option, ... nothing). In a program (.exe) that works, there is a MSComm.ocx and a comdlg32.ocx files, that maybe is the key to correctly connect my computer to the treadmill, and send my ascii code)

Are you using 32 bit MATLAB or 64 bit MATLAB?
