I'm trying to send text strings out the serial port of the BSII.
I am able to send single characters to DCE equipment, but I am unable
to send text strings to DTE equipment. I've disconected the ATN line
on the carrier board, but still no data.

Any suggestions?

Todd

    Hi,

    Normally DTE and DCE equipment have their TX/RX pins (2 and 3) swapped.
    Check your cabling documentation..

    Greetings peter

    All of that DTE / DCE stuff confuses me -- here are a few things that come
    to mind that may be of use.

    The transmit and receive lines on a cable to connect a 25-pin serial port to
    a 25-pin modem do not cross.
    The transmit and receive lines on a 25-pin to 25-pin null cable do cross.

    The transmit and receive lines on a cable to connect a 9-pin serial port to
    a 25-pin modem do cross.
    The transmit and receive lines on a 9-pin to 25-pin null cable do not cross.

    If I remember right, the rules for the 25-pin to 25-pin cables stated above
    also apply to a 9-pin to 9-pin cable.

    Adapters used to connect a 9-pin mouse to a 25-pin serial cable rarely have
    all the connections necessary to use them for anything other than the mouse.

    My first message was a bit vague. The problem is not cabling because
    I am getting communications. The problem is when I send a text
    string all I receive is a NULL character from the stamp. I've tried
    sending one character at a time and several other methods. Still all
    I get are NULLs.

    Please Help.

    Hi,

    Have you tried/checked lower baudrates yet. At some equipment
    that use software decoding a too high baudrate causes them
    to miss transients. A 1200 baud setting always should work.

    Greetings peter

    > SEROUT 1,17405,[noparse][[/noparse]65]

    This specifies I/O 1 and a baud rate of 2400--won't work.

    To send data back to your PC, use the DEBUG command or send via I/O
    16 at 9600 baud:

    DEBUG 65 ' dec 65 = hex 41 = ASC 'A'
    or
    SEROUT 16,16624,[noparse][[/noparse]65]

    See BASIC Stamp Programming Manual 2.0 pages 97 and 297.


    Regards,

    Steve

    I have just started trying to learn the SEROUT command. When I
    download the simple program:

    SEROUT 1,17405,[noparse][[/noparse]65]

    to my BS2SX, should it give an output to the debug terminal? If so,
    something is wrong b/c I don't see anything.

    This would send the data out Pin #1. You can send this data to the debug
    terminal by using Pin
    #16.

    I tried that too and still nothing. I have the debug window set to
    the right baud rate and everything so I'm not sure what the problem
    is.

    That worked, thanks. Why does the baud have to be at 9600?
