Toshiba Laptop and BS-2 Problem

HI Gang:
I have a problem communicating with my BS-2 with my Toshiba Tecra 8100
laptop. I get the dreaded "No Basic Stamp found" message. It is running
windows 2000 Professional. My BS-2 is fine since I can program it with my
Dell P-3 computer running windows 2000 Pro also. I have checked the serial
port settings on both computers and they are identical. Any suggestions??
Thanks,
Al Sines, W3AL

You seem to be having the same problems a nephew of mine is having, except
his is on a Dell 2500 Desktop. I can communicate with his Stamp 2 using
either my Compaq (Older one) laptop or my Packard Bell Desktop, or my Dell
4500 desktop, but he cannot seem to get his Dell to communicate with it. It
would appear that the problem is not computer brand related. If I find the
solution I will, of course, let the list know and please if you find it first
let the list know. It is strange.

Dont have this laptop for problem, but I remember reading posts about the
problem. I believe you have to disable FIFO on your lap top. There is
information at the Parallax web sight.

the PC. Newer computers and laptops have +/-5V on the RS232.
If it were designed to be truely compatible with rs232 it would work
down to the +/-3V levels.
The problem is related to newer computers in general. I suspect most
manufacturers have switched to lower voltages for power savings
resons (never to return); however, the problem lies in the bs-2
design. It will have to change.
Seems the voltages on the RS232 chip are not exactly
true levels. Try plugging it in. It may work, it may not.

max233 rs232 driver, I use one with bs2 to make true rs232 from 0-5v out of
my stamp. It requires no external caps etc, and will boost the voltages to
around 12 to -12 volts.
Jan Axelsons book "Serial port complete" has all the schematics etc.
Cheers,
Chris

I have been using Toshiba Laptops to talk to Stamps since they were invented.
I started with a 486, and three Satellite models, and now have a PIII 700 MHz
Satellite without a serial port. I had to buy a Keyspan USB to Serial adapter
for this computer. All have worked fine with the Stamp II's and a 25 foot
serial cable, in a welding shop.
I would look for other problems, or it may be a problem with your particular
computer.
Hope this is not redundant information, I did not see the first part of the
message.

datalogger if it is set to high power mode. It works fine with everything
else, including Stamps.
Odd, I have a Satellite Pro which needed the FIFOs disabled, and a friend
experienced the same thing on another Toshiba, not sure of the model.
Several other members have found this fix to work as well. Wonder why your's
are ok?

My Toshiba laptop is now talking to my BS-2 and BS-2p. It was the FIFO that
had to be disabled. I goofed initially and failed to uncheck the "automatic
configuration" once that was done and set to "use current settings" (current
settings with FIFO disabled) it worked perfectly.
Again, thanks to all.

(Sorry, forgot the model number).
"232 settings" usually means something like
baud rate, parity, stop-bits. It doesn't usually
include FIFO buffer setting -- BUT my Toshiba
REALLY complains if you try to program a BS2 with
FIFO turned on (and it won't program it).
Win 2000 Easiest fix:
Click Start, Settings, Control Panel.
Select System, Hardware Tab, Device Manager button.
Click 'Ports' entry. Double-click the Com port you want.
Click 'Port Settings' Tab. Click 'Advanced' button.
-- Finally, you are on the right page!
-- Thanks Microsoft.
Click on the 'Use Fifo buffers...' check box, so it
is CLEAR. Click 'OK'.
You don't need to reboot your PC for this to work.
You COULD lower the 'Transmit Buffer' and 'Receive Buffer'
settings to 0 to get the same effect -- but clicking the
'Use Fifo buffers...' box is easier to undo.
Good luck! AllanL
