Ah, hah. I have this one bite me a lot. At work basically everything I build
uses a serial port, windows on some machines has a habit of moving the com
port around, windows programs still work fine, but DOS goes nuts. Com1
becomes com2, etc... Even on a laptop with 1 com port. Windows accesses com1
and DOS programs access com2, and they are the same port. I love Microsoft!
It may not seem possible, but I've seen it on several occasions.

Ray

The older machine (IBM 50Mhz) works fine with the DFI,  Uses COM 1.  

The newer machine uses COM1 also, same address, same IRQ, and I have to
assume
it is enabled because its the same port used to talk with the data recorder
and the MSD (only difference is DFI is run under DOS, while the others are
in 
Windows).  

Both are using COM1, however, I am not certain if the newer Compaq Presario
1200
enables the Com1 port while in DOS mode.  

The Operating system on the newer machine is WIN 98.

Steve, have you verified that the serial port is enabled ? I used to support
a lot of IBM Thinkpads and quite a few came in with the serial port
disabled. Also are you sure of your com port setting ? What com port were
you using with the Accel ?


Raymond

I recently upgraded my laptop to a Compaq presario 1200.  My intention was
to
get rid of my 50Mhz old machine and have something that runs windows.  I use
this laptop at the racetrack to run my data recording software (windows),
MSD
software (windows) and my Accel DFI software (DOS).

The problem I have (and Accel will not support) is that the newer laptop
will not
connect to the DFI.  I have changed the baud rate to match the rate of the
older
50Mhz machine,  same stop bits, same parity.  Not sure which flow control so
I tried
all three (xon/xoff, hardware, none). I even lowered the size of the
buffers.  After
many configurations and attempts my result was still failure.  I even tried
slowing
down the newer PC to match the performance of the 50MHz machine.  I have
started in
Dos mode also.

My dilemma is the old PC is on its last legs, and I need to make the newer
PC communicate
with the DFI.

Does anyone have any ideas, above and beyond what I have already done to get
my new
PC to link to the DFI?

Does anyone know what is different between older serial ports (on an IBM
50Mhz machine)
and the newer (500Mhz + machines)?????

Can a device be built that will let the newer serial port work the same as
the older
serial port????

Thanks for you help.

PS: please reply both to the page and directly to me, I am not on the efi or
gmecm lists
any more, just the diy list.
