NOt sure if you figured it out yet or not. IF the drivers don't have an import method option, then you will have to emulate the "Send Text File" of the hyperterminal to send method. The other option is to just program your "method" as labview code and manual step through it in your program and issue the corresponding commands.
From the PHD ULtra Manual:
IMPORTING A METHOD FROM AN EXTERNAL COMPUTER
Follow these instructions to import a Method from an external computer.
1. Connect the pump to the external computer via a RS-232 or USB cable and set the Address value to
‘00’ using the Set Pump Address command in the Settings menu.
2. On the computer, open the HyperTerminal application and verify that the computer can communicate
with the pump.
3. In HyperTerminal, click on the Properties icons and choose the Settings tab on the pop-up box that is
displayed.
4. Click on the ASCII Setup button.
5. In the Line Delay field, enter 500. This will set a 500 millisecond delay after each line is transferred
during the import process.
6. Click OK twice to return to the HyperTerminal Main Menu screen.
7. In HyperTerminal, choose Transfer→Send Text File...
8. Select the Method that you want to import to the PHD Ultra pump and click Open.
9. Before disconnecting, verify that the Method was transferred by choosing Method Select from the
Method Main screen at the destination PHD Ultra pump, then browse the Method menu to confirm
that the new Method is now saved at the pump.
