# Hercules serial echo mode

## Question

Asked by elephant on 2014-06-05 in Serial-to-Ethernet & ConfigTool.

Hi,

I am using Wiz107SR and using Hercules to monitor the traffic. In Hercules serial mode, how can I put the device into echo mode? I am successfully sending data to the device and monitor in hercules but I would like to receive back the data like echo.

Thanks and best regards,

Hi, elephant.
WIZnet ‘Serial to Ethernet modules’ (like WIZ107SR) are not support Echoback.
If you want to check the data transmission successfully, Hercules program setting to a TCP client and data exchange through serial terminal to TCP client…

To be set as follows.

H/W :
PC |===== Serial and LAN(Ethernet) =====| WIZ107SR

Data exchange path :
TCP Client (Hercules program, PC) - WIZ107SR - Serial terminal (PC)

Hi,

I implemented a python script to communicate the unit. In hercules serial interface, I can see the data Which I am sending from python. I would like to reply through serial side to my python script that I can test my python script. In this way, I can only test when I am writing to the unit but not be able to test when I am reading back from the unit. If I do it manually, it is too late. is there any way I can do this in another way?
