    I advise not to run DNet faster than 19.2KBaud on the built in serial
    port simply because a standard Amiga cannot receive faster without loosing
    data... you wind up going slower due to packet errors.  That's all.  Since
    both DNet and terminal programs use the serial.device one assumes the
    same problem would occur with the terminal programs.

    People who hack their own serial.device's (for example, to run at MIDI
    speeds without loss of data) can get better results but I do not know of
    any terminal programs that do that.

    And, of course, smart serial cards such as those you can plug into an
    A2000 can usually be run much faster.

    UNIX systems tend to barf on serial at high data rates.  Generally, the
    kernel buffer (usually 256 bytes) will get full before the user task
    has a chance to drain it with read(), causing lost data.  The problem can
    normally be avoided by using a 7-wire (e.g. RTS/CTS) interface which is
    certainly possible if you are directly connected.

    The only limitation with the SUN or whatever is the maximum baud rate the
    serial port hardware understands, and the maximum baud rate supported
    by the IOCTL call.
