    Re: Need some help with com port reads

    The problem I see looming is that in the cases where no CRLF is sent, you don't know when you've received everything, unless you know that after sending a particular 'command' you know how many bytes to expect back. Don't suppose the other end can be modified to always send a terminating CRLF can it? It would make life much simpler.

    EDIT: With respect to the 4 ESCs - I gather that you actually want to send as many as are required to get back to the main menu (?) If so, then you could go through a process like

    Do
    Send an ESC
    Loop until Device responds with Main Menu Or it times out
