For those of you who prefer the Windows environment, the UltraScan 
software package for Windows and Origin (TM) includes a program
that allows you to do the same, i.e., watch data in real-time as it is 
being acquired. It probes the serial communications during data acquisition
of the XL-A program and displays data in graphical output format on the 
computer screen. We have been using this program for about 1-1/2 years now
and have been able to save many samples, when the program indicated that the 
XL-A ran too slow or fast for a particular sample. After the first couple of
scans one can usually tell by looking at the graphical output if the XLA
needs to be slowed down or speeded it up. I believe that this kind of 
software is essential for velocity runs, because one definitely needs
to check if the speed is correct if the molecule(s) under investigation
are unknowns. The whole UltraScan program will soon be available for UNIX
environments, like sunOS, solaris or linux. The program is only commercially
available (including lot's of other stuff), but this way you don't have to 
switch your entire operating system and software over to desqview.

Happy data acquisition, -Borries Demeler
