# WIZ107 and CTS signal

## Question

Asked by JulesMhz on 2017-09-27 in Serial-to-Ethernet & ConfigTool.

Hello,

I would like to convert RS232 to Ethernet in my project. But I need to handle CTS signal flow, for example, receiving an UDP packet each time CTS goes high. Is it something possible with this chip ?

Thank you.

Best regards.

Julien.
