I'm trying to understand how this library is handling the write single register function 
(Modbus FC06).

As far as I can tell, modbus_writeReg is actually calling modbus_writeRegs without a 
register count, which I don't understand.  The details of parameter passing between 
Scilab and c libraries are a little beyond me so this may be OK.  If it was calling 
modbus_writeRegs with a register count of 1 it would be logically equivalent to 
modbus_writeReg but using Modbus FC16.

The reason for my interest is that I am dealing with an instrument (Honeywell UDC2500) 
that refuses FC16 with a count of 1 for writing a single register.  It works with FC06-- 
not very logical but when your name is Honeywell, you can pretty much do what you like 
and who can argue!

The other thing I noted is that the modbus_writeReg example code in the help 
documentation calls modbus_readReg function which doesn't seem to exist.

I have high hopes for this library to be a big help in the kind of work I am doing but 
figuring out the details to get going has got me puzzled.

Any advice would be welcome.
