It depends the instrument must support some sort of RS232 comms then
it is possible. However you must determine what protocols are used.
If its Modbus or similar there are VBX's available. Otherwise you may
have to write your own driver. This maybe possible with the
MSCOMM.VBX that ships with VB3 if its fast enough . You will have to
find out what the data means by either the manufactures information or
a protocol analyser.
