    You have addressed an issue that I believe is the same or related to what I
    have seen on a system we have set up here in southern Indiana. There is an
    Ethernet link between a Linux node and a box running BPQ. If a user comes
    in on AX25 (radio) and connects to the BPQ box, everything works fine.
    However, if a MS Windows machine on the Ethernet LAN telnets into the node
    and then connects to the BPQ box, things get a bit crazy. It appears that
    additional characters are being appended, even before the ENTER key is
    pressed (if memory serves me correctly). This makes the connection useless.
    It is impossible to issue node commands, or access the weather server
    attached as an application through BPQ's host interface. The exception to
    what Roger describes below is that this is happening in the text mode.

    I had hoped to research this a bit more before posting, but Roger's problem
    sounds like it is the same thing. Any help you guys can offer would be
    greatly appreciated.
