autodial: Uses a modem to automatically a number (or sequence of numbers)
	It then passes control over to you. (i.e. you pick up the phone
	and then the modem hangs up).

Usage: autodial <options>

Options:
	-n <number>	Add dialing digits <number> to dial sequence.
	-s <number>	Add sleep time <number> to dial sequence.       ","
	-w 		Add a wait for silence event to dial sequence.  "@"
	-t 		Add a wait for dialtone event to dial sequence. "W" 
	-e 		Add a string to be eval'ed to dial sequence (hack).
	-F <file>	Read the number to dial from <file>

	-d <dialstring> Use <dialstring> instead of stuff from -n,-s,-w

	-b <baud>	Set baudrate to <baud>
	-l <line>	Use modem at /dev/<line>	(ttyS0)
	-i <initstr>	Init strings for modem.   Separate cmds with "|" sign.
			Or use the "%" instead.
	-f <finistr>	Finish strings for modem. Separate cmds with "|" sign.
			This is after user response, but BEFORE ATH.  ()
	-r <resetstr>	Reset strings for modem. Separate cmds with "|" sign.
			This is AFTER ATH.  ()

			"%" may be used as separation char instead of "|"

	-pty		Start the remote modem in a pty and then exit.
			(use -l host:device)

	-x 		Launch in an xterm.
	-X		As -x, plus additional X-window prompts. 
	-display <dpy>	Set DISPLAY to <dpy>, implies -X.

			Each of -x, -X, -display <dpy> MUST be the first
			option on the cmdline.

	-L, -list	List available modems on modem host.
	-listall	List available modems on all hosts.
	-local		List available modems on local machine. (must be first arg)
	-v		Verbose extra info (must come first)

	-hook <cmd>	Hook to run a command after the connection.
	-p		Pause and prompt before exiting.
	-np		Do not pause.
	-debug 		Turn on debug output.
	-D 		Display scrubbed number and exit.
	-DD 		Print dialstring and exit.

Notes:
	Here is an example:

		autodial -n 18887862786 -s 8 -w -n 123456789

	where "123456789" is a secret code that needs to be entered.
	The "modemese" dialstring created out of this would be:

		ATDT18887862786,,,,@123456789

	The list of modems is in the file: /home/runge/.modems.
	This program should be used as a interface to that file.
	with the -L, -list, -listall, -local, and -v switches.

	programs that might be needed:
		people, selection.tcl, tkquery, disp
		stty, xon, rsh, xterm, xwit, whoami, id, hostname
