    As I am new to this group please excuse me if my questions have already been
answered by previously posted articles.


    I am working on a realtime PC program that uses a very high baud rate
 serial card to aquire roughly 1Mbyte of data from a remote probe.  The problem 
is that I cannot write to the drive while accepting data from the serial stream,
the timing is too tight and I lose data.   

    Is there a reasonable way to write, during runtime and without using a 
virtual disk drive (same problem!), to the memory in my machine above 1M ??  
(It seems like it can be done, the virtual disk device driver does it. )


    I would greatly appreciate any references to published material and/or source
code fragments (in C or 80286 asm please) that would help me solve this little 
problem.
