Marcel Moolenaar 35777a2a79 Don't use a time-limiting loop that's defined in terms of the baudrate ... in the putc() method. Likewise, in the getc() method, don't check for received characters with an interval defined in terms of the baudrate. In both cases it works equally well to implement a fixed delay. More importantly, it avoids calculating a delay that's roughly 1/10th the time it takes to send/receive a character. The calculation is costly and happens for every character sent or received, affecting low-level console or debug port performance significantly. Secondly, when the RCLK is not available or unreliable, the delays could disrupt normal operation. The fixed delay is 1/10th the time it takes to send a character at 230400 bps.		2007-04-03 01:21:10 +00:00
