Help on Chatting The 'Chat' command allows the caller to chat with the host op- erator. When the caller presses 'C' the host operator is paged for 20 seconds. If the host operator responds, you will see him/her typing on your screen. If you can, place yourself in Chat Mode, by using your comm program's chat mode (Telix's is Alt-Y). You will then see what you type on half of the screen and the operator's words on the other half.
