    No serial port in Arduino

    I use Arduino software with Teensyduino.

    However, I cannot write programs to Teensy 2.0 because I cannot select serial port.
    I cannot operate serial port menu.

    How can I write programs to Teensy2.0 with Arduino ?

    I give classes in univ. by online.
    Some student cannot write programs with their PC.

    I resolved.

    In Arduino,
    Select Teensy2.0 for Tool --> Board menu.
    In this state I cannot select a port for Tool --> Serial Port menu.
    Next Compile.
    In Teensyloader,
    Auto off. Open HEX file.
    In Teensy2.0,
    Push a button.
    In Arduino,
    I can select Tool --> Serial port --> hid*********(Teensy2.0).
    Then I can write a program to Teensy2.0.

    I can write a program to Teensy2.0 for PC having com port.
    I cannot write a program to Teensy2.0 for PC not having com port.
    I resolved as stated above.
