Hello you programming gods out there in netland.  I have a question that has
been bugging me for a while, and I can't find the answer in any reference
that I have.

I need to access a two dimensional array declared in C from a ASM routine.
To throw a wrench in the works, this ASM is a serial interrupt handler.  I
have already written the routine in C, but want to convert to ASM to cut
down on the speed.  (Those damn 32400 baud RS-422 lines.)

For example the following C declaration:

char rx_buffer[6][256]

I want to be able to put in my character from the serial port into the above
array from assembly.

Thanks for the info...

Please respond by Email and I will post a summary.
