Help with RS232 PLEASE !!!


I need a converter of the original RS232 that works exactly like in the old computers. I bought Sweex Converter, Stlab usb to rs232 cable converter, and STLAB express card rs232 none of them worked!

We are using an old program in DOS that need the *exactly* RS232 interface, if not it cannot communicate.

Someone know express card or a USB converter that works like the original RS232?

Please help!!!

Thanks in advance,
