C++ (Cpp) ser_purge Examples

Example #1

File: gsm.c Project: derkling/adcontrol

static int8_t _gsmWriteLine(const char *cmd)
{
	size_t i;

	// NOTE: debugging should no be mixed to modem command and response to
	// avoid timeing issues and discrepancy between debug and release
	// versions
	gsmDebug("TX [%s]\n", cmd);

	// Purge any buffered data before sending a new command
	ser_purge(gsm);
	// Clear error flags
	ser_setstatus(gsm, 0);

	// Sending the AT command
	WATCHDOG_RESET();
	for (i=0; cmd[i]!='\0'; i++) {
		kfile_putc(cmd[i], &(gsm->fd));
		WATCHDOG_RESET();
	}
	kfile_write(&(gsm->fd), "\r\n", 2);

	return i;
}
