Physics Dept., W. Lafayette, IN Lines: 7 In-reply-to: ray@maxwell.physics.purdue.edu (Ray Moody) Writing faster serial routines is not the right way to speed up a communications protocol. Even with super-fast serial I/O, 100% efficiency cannot be obtained. In order to reach 100% efficiency, it is necessary to write serial routines that are not affected by the RS-232 interrupts. Ray
