#2320, "The Solution for Serial port...."
In response to In response to 32




          

Sup guys..
Ok, after I had PAIN for 5 days.
Just so maybe you guys can check this out later on if you hvae problem as well.

I bascially did this on my laptop, and OH YEAH, it's working like a charm.

Just go right click MY COMPUTER, click on Properties, pick the HARDWARE tab, click on DEVICE MANAGER, click on the '+' under the Ports (COM & LPT),

in there, you should see the Serial Port (COMx), the one you want to use for your MS. the one that you installed or added to your laptop or PC. (either USB-Serial, PCIMCA Serial Port, etc...) double cluck on that hardware (port)

And now a new window pops open.
There are two ways.
1) for some computers, it will have a tap called FIFI Buffers, or Advanced Setting
2) for some computers, it is just under the PORT SETTINGS tab, and click on the ADVANCED.. button

Once you in there (TAB<1>, or new page<2>) just UNCHECK the "Use FIFO buffers (requires 16550 compatiable UART)" (don't use it) (UNCHECK IT)

Then try it out again.
Your serial port should work perfectly now =)

The reason is because if this feature is on, it will buffer the data transmitted through the serial port, and when the buffer is full, then write out the data. this is useful if your serial port is very fast, or if the device connected to your serial port is too fast or too slow compare to your serial port. But in our case with MS. it is not. so buffering the data will only corrupts them and make the connection not stable!

Try it. it will help ALOT!

Thanks all again for your help. especially XtremeRS.

Later. back to more tuning and reading
Gil
