HC-05 repeating response in PUTTY terminal

Projects Interfacing w/ Software on the Computer
1

I am using a linux desktop (ubuntu) and communicating with an HC-05 module using Putty.
I am communicating with an HC-05 via an usb-to-serial converter.
The problem I have is when the HC-05 responds it keeps responding until
I hit the Esc key.

Here is a a screen shot where i entered AT+PSWD and HC-05 keeps responding. I have tried playing around with the Terminal parameters in Putty but no luck.

I have a dual boot machine and everything works using windows and TeraTerm. I normally use
linux though.

Thank in advance

Initiali(s/z)e a "responded" flag. Enter the main program and test the "responded" flag. If "responded" is clear, enter the "make a response" routine. Immediately set "responded" flag and make a response, which should make the main program not enter the "make a response" routine.

A main program does not exist. Just putty talking via usb->serial to HC-05. I am typing in AT commands in the terminal.

Can you make a loopback and see what you send? (no HC05, just a loopback at the serial end - 2x3, 4x5, 6=8=20)
