Anyone have experience with an Istec series 1800 water meter with a Model 9305 display with Modbus interface?
I'm having some issues configuring the interface as it defaults to 300 baud. There instructions are very outdated. They even include a BASIC program that you should use to set up the configuration. How long has it been since Windows supported BASIC? Hyperterminal access does not seem to work either.

Any help or advice would be appreciated.
