    Can you have more than one Serial Port connection open at a time
    on a Pocket PC PDA ?

    The PDA has a Compact Flash RS232 serial port card that plugs into
    the PDA's Compact Flash slot with a short cable and a 9-pin D-Shell
    connector for a hardwired serial port connection using Com1.

    The PDA also has Bluetooth capability and uses Com8 for the serial
    port connection.

    Can both Com1 and Com8 serial ports be open at the same time?

    Does the Serial2.dll support multiple Com Ports being open at the
    same time on a Pocket PC device?

    I have a project that uses 2 Pocket PC PDAs. One PDA will be
    placed in a fixed location and connected to a control box using
    the hardwired RS232 cable. The 2nd PDA will be mobile and it
    will communicate with the fixed PDA/control box using the Bluetooth
    wireless link.

    Yes. You should add one Serial object for each connection.

    Multiple Bluetooth?

    I know it might be related to the operating system, but could you also have muliple serial bluetooth connections?

    It is possible with multiple Bluetooth drivers.
    AFAIK a single driver can only handle one connection.

    No problem, on my Kaiser I'm connecting to my Bluetooth watch on COM6 and external Bluetooth GPS on COM5 simultaneously with no problem.
