How can I use digital I/O for a serial connection

I have the following problem. I need to capture/generate analog and digital signals. This also needs to be synchronized to the data captured from a UART on a serial connection. The problem is that all the data needs to have a common timestamp, i.e. the digital, analog and serial data must have the same timebase for comparison. Now, I know this is not possible with a 6036E because it only has static I/O lines. The M-seris has hardware-clocked digital lines, and I think I can set up sychronized analog/digital I/O operations using one sample clock. How would I synchronize this with the read serial data. My first thought was to implement a serial link using the clocked digital I/O on the M-series card. Does anyone have any idea how to do this?
Thanks.

I am not to sure how you would setup the serial side of things, but the following example will get your along way in synchronizing your digital I/O and analog I/O on an M Series board.

Maybe if you describe your serial application a little more, I or someone else on the forum will be able to help out.

The aforementioned example:
