I've done some microcontroller work over serial also. Unfortunately, interfacing with a serial port is system dependent, and the mechanisms can be quite different, as you probably know. It appears that Simon has a solution below that will work if you are willing to accept the default baud rate (960

r-devel list, I have recently written an R package that solves a linear least squares problem, and computes the multivariate normal density function. The bulk of the code is written in C, with interfacing code to the BLAS and Lapack libraries. The motivation here is speed. I ran into a problem com
