Cox 4020 (4000 series) Flow Computer

I’m attempting to communicate with a Cox 4020 flow computer over serial.

It’s a fairly popular flow computer, so I’d figure I’d ask around to see if anyone knew of a driver.   My google-fu let me down in my search.

If not, how do you configure the serial port? The thing is expecting 10 bit characters.

See page 32 of http://www.badgermeter.com/Badger-Files/PDFs/Industrial-Products/40104020FlowComps.pdf

The VISA Configure Serial Port Vi does not give options beyond 8 bits.  

The only thing I could think to do is to convert each character to a Boolean array, append all the arrays representing multiple characters to each other, then convert it back to a string.

The only part that worries me, is what to do if the number of appended bits MOD 10 isn’t zero.. I don’t know if the meter will barf or not with extra bits..

Before I go to far down the rabbit hole, figured I’d ask if anyone has been down it first, or had any insight.

Thanks!
