The Platfrom SDK November 2001 says the following about 'comm/datamodem/portname':
quote:
The comm/datamodem/portname device class consists of the device names to which modems are attached. When this device name is specified in a call to the lineGetID function, the function fills the VARSTRING structure with a null-terminated ANSI (not Unicode) string specifying the name of the port to which the specified modem is attached, such as "COM1\0". This is intended primarily for identification purposes in the user interface, but could be used under some circumstances to open the device directly, bypassing the service provider (if the service provider does not already have the device open itself). If there is no port associated with the device, a null string ("\0") is returned in the VARSTRING structure (with a string length of 1).

So, according to this, there are provisions to read the data. But, not knowing the communications protocol used by the multimeter, I doubt it'll be doable in kiXtartat all. I would rather use some kind of command-line data logger that reads the data into a text file. Afterwards I can parse the text file with KiXtart and do whatever needs to be done with that data.
That reminds me, it would be nice to be able to define a function based on a call to a DLL as can be done in Visual Basic.
