Native Function to Slave devices

[timoteo7]

Hi!
First, I would to thank you for your wonderful library.

Can you help with some code to Native Functions in Slave Devices ?
I tried that:

var native = require('modbus').native;

var ctx = native.new_rtu('/dev/ttyACM1',38400,'N', 8 ,1 );
native.connect(ctx);
native.set_slave(ctx,1);
var rc = native.read_registers(ctx, 0, 1, tab_reg);

But it doesn't seems to work.

Can you give some help with that?

Thanks in advance,
