Serial Communications Echo Ignore


Recommended Posts

Some serial devices actually echo the read command. For instance a Modbus ASCii half duplex device I have always echos the command sent to it (can't be disabled because of the circuitry) and then sends the result of the request with some time delay between them.

Is there any easy way to ignore the echo and only accept the real reply? I think I have searched all the forums and not found anyone asking this one.

I realise I could start writing code to do it but I thought that someone may have an easier solution
