You can do a lot of things. I'm not sure what a custom card has to do with rs232, but included with LabVIEW are the VIs called INPORT and OUTPORT. These will send/receive data at any I/O base. So if you know what I/O base your card is at, you can send to it and receive from it.
thanks for the answer. my custom card read and write with a rs 232 port. are you talking about visa controls?

LabVIEW is a handy development tool if you want to control/read-out serial RS-232 devices. In my compact company custom (RS-232) hardware is developed, so I communicate via this bus a lot. In the beginning of LabVIEW one only had the serial I/O vi's. Although after some years VISA was introduced as a better solution for communications, the plain old serial vi's still work well for a lot of demanding users. The choice is up to you.
