Should be
Code:

rxin = (rxin+1) % rxsize;


You have a '\' in there that should not be there.

% returns the remainder of the integer division.

This will accomplish the same and may be more clear
Code:

rxin++;
if (rxin >= rxsize)
  rxin -= rxsize;

or
Code:

rxin++;
while (rxin >= rxsize)
  rxin -= rxsize;
