Lines: 24 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. Thank You Potter
