No Stamp Found

Hi All, I saw another post on this topic but it didn't seem to go far.

I just got back into the Stamp scene, dusted off the prototype
station and hooked up with my laptop. No Stamp Found.... The stamp
(BS2-IC circa 1998/99) still has my last program in memory and
otherwise appears to be running fine.

What's new with my setup is that I am using a Toshiba laptop with the
latest Stamp application in Windows XP Pro. I have configured the
program (Stamp v2.0b1) to use COM1 (COM3 is my modem) - the program
detects the loopback and nothing else. I have bypassed the original
serial cable with a new one, so I think that part is fine - even
changed the power supply. Is there any known issues with newer PC
hardware/software that I should address. The last time I had working
communications was with an old DOS 386 which I no longer have.

Thanks,
Mike

    Yup, Toshiba's have a knwon problem recognizing Stamps when their
    Serial FIFO is 'too high'. In Control Panel, System, Serial Devices,
    Com devices, Advanced -- either disable FIFO, or reduce FIFO to 0.

    Does the laptop have "FIFO" enabled for the COM port? I use a Toshiba
    laptop and, just before I installed the stamp IDE, someone answered a
    previous question about having to disable it on a Toshiba to get the
    communications with the stamp going. I did the same, and it's worked for
    me. On NT, FIFO is an advanced setting for a COM port.

    I never tested with FIFO enabled.
