From Google:

I am doing serial communication port with a multimeter mastech mas-ala 345 and time to connect with the card (usb to RS232 national instrument)

do not send me any byte

 

See if this thread helps.  It talks about needing to power the serial lines by setting some of the handshaking lines.
