2 * This header file defines the loop-count timeout value that should
3 * be passed to the rx_sim_byte() function. By the spec we have to wait
4 * 9600 etu's; at 3.25 MHz SIM clock and the default slow mode (no speed
5 * enhancement) this 9600 etu number translates to about 1.10 s.
6 *
7 * The constant defined here has been calibrated empirically; the measured
8 * timeout is about 1.38 s, giving us reasonable safety margin.
