ringtools/imy: fix duplicate definition of tdma_durations[] The bug was reported by Vadim Yanitskiy <fixeria@osmocom.org>, although the present fix is slightly different from the contributed patch: because main.c doesn't need this tdma_durations[] array at all, let's simply remove the reference to this array from main.c rather than turn it into an extern. I no longer remember my original thought flow that resulted (by mistake) in tdma_durations[] being multiply defined in main.c and durations.c. My intent might have been to define all globals in main.c and have the reference in durations.c be an extern - and I missed that extern - but without clear memory, I have no certainty. In any case, having this data array defined in the same module that fills it (durations.c) is sensible, so let's make it the new way.

#include <sys/types.h>
#include <strings.h>
#include "types.h"
#include "simregs.h"

extern int serial_in_poll();

int enable_poll;

void
poll_sim_rx()
{
	u32 drx;

	if (SIMREGS.stat & SIM_STAT_FEMPTY)
		return;
	drx = SIMREGS.drx & 0xFF;
	printf("%02X ", drx);
}

int
mygetchar()
{
	register int c;

	do {
		if (enable_poll)
			poll_sim_rx();
		c = serial_in_poll();
	}
	while (c < 0);
	return c;
}

void
cmd_poll(argbulk)
	char *argbulk;
{
	char *argv[2];

	if (parse_args(argbulk, 1, 1, argv, 0) < 0)
		return;
	if (!strcmp(argv[0], "on"))
		enable_poll = 1;
	else if (!strcmp(argv[0], "off"))
		enable_poll = 0;
	else
		printf("ERROR: \"on\" or \"off\" argument expected\n");
}
