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