# Passing ctrlC through to serial port on WIZ6000

## Question

Asked by arg02 on 2014-03-12 in General.

With a telnet session open to the WIZ6000 one one end and a serial connection session on the other end i can happily pass text back and forth through the WIZ6000 to both sessions.
But i can’t pass ctrlC commands though, ctrlC is also known at [ETX].
See screenshot below. - Any advice?

Hello arg02

As we replied via e-mail, if you use general TCP client(not telnet client), you can send any raw data(0x01 ~ 0xff).
Refer to the below screenshot.
