USRobotics V.34 user manual Answer Mode, AT S0 = 1 Enter

COURIER HIGH SPEED MODEMS

	The cycle continues until the modems connect or the modem
	reaches a maximum of 10 attempts. The 10-try limit is
	mandated by Industry Canada (IC) to prevent tying up local
	telephone company exchanges with unconnected calls.
A>	This command combines the features of both the A/ and >
	commands. The modem enters Repeat mode as described
	above, and redials the Dial string in the command buffer. Like
	the A/ command, A> does not take the AT prefix or a Carriage
	Return.
	Exit Repeat Mode
	Should you use > or A> with a command other than a Dial
	string, abort the cycle by pressing any key.
	To abort automated redialing, be sure to press any key when the
	result code appears, during the pause before the modem begins
	dialing again. If you press any key while the modem is dialing,
	that dial attempt is canceled but the cycle continues.
