I use grind degrees PCI1710 acquisition data, in through the VB controls the data acquisition, acquisition frequency about 2 ms

Acquisition of the data in VB is a real-time change (about 2 ms change again), how this data can be recorded,

Such as gathering for 20 minutes, how to record this value for a short period of time, and make the trend chart, use a database or??? .

Personally think that can use the list,

Array can be deposited in the database table or variables, can be convenient to connect to the MSChart control data source to real-time display,

This is the data acquisition card PCI interface, has nothing to do with a serial port, you can define an array of big enough, the data stored in the array, and then stored in the database,
