 use Device::Modbus::ASCII::Client;
 use strict;
 use warnings;
 use v5.10;
 
 my $client = Device::Modbus::ASCII::Client->new(
    port     => '/dev/ttyUSB0',
    baudrate => 19200,
    parity   => 'even',
 );
 
 my $req = $client->read_holding_registers(

 my $resp = $client->receive_response;

DESCRIPTION

This distribution implements the Modbus ASCII protocol on top of Device::Modbus. It includes only a client, Device::Modbus::ASCII::Client, which is based on Device::Modbus::Client. See this last module for the core of the documentation.

This distribution came to life thanks to Stefan Parvu from Kronometrix. It was his motivation, dedication and support that made this module possible.
