Serial Console: No input

[KNERD]

Hello.

I am having issue with one distro so it was suggesting I use the serial console to access to see if the distro was booting correctly.

While I see the distro properly booting, but when I try to log in I am not getting any response when I try to type in.

I am using a Prolific PL2303TA based cable with the following pins

Black cable-----GND
Green cable-----TXD
White cable-----RXD
Red cable -------VCC

I have Green connected to pin 8, White connected to pin 7, and Black connected to pin 6

Any ideas on why there is no input?

Thanks!
