This is the help for vth.

available commands are:

start		commences connection between your terminal and
		the modem.  This connection is broken when you
		type the COMMAND_CHARACTER, which is initially
		set to character one, control A, and can be
		changed by the escape command.

escape		allows you to change the escape character.
		vth will type out the present value (numerically)
		and you will be asked to type in a new value,
		also numerically.


@<file-name>	starts reading commands from the named file.  These
		command files do not nest.  If the file contains a SEND=
		command, then after the file is transfered, you will be
		placed in == mode, rather than transparent mode.  Therefore
		you can have a command file to send several files.

vms		spawns a subprocess for you
		
wait		allows you to specify a delay for each line, for the
		send command.  The value is an integer, expressed in
		hundredths of a second.  (eg.  550 means 5.5 seconds)

restart		goes into transparent mode with out reseting modem.
		This command is meant to be used if you are allready
		on a remote machine, and you wish to turn the logfile
		on or off.

logfile=	turns on the logfile feature.  The rest of the command line
		(after the =) will be taken as a file name, and a record of
		everything you do will be put into that file.

uline		causes all input to the logfile from your
		terminal to be underlined. so that the log file will
		be appropriate for documentation of a terminal session.
		PLEASE NOTE that it requires halfdup to be activated,
		and the remote machine to be set to no echo.  In full
		duplex mode, the command file is only made up of
		output from the other machine, including the echoing.
		Since the program does not know which output is echoing,
		and which isn't you must use halfdup mode.  Additional
		ramifications are that vth will supply echoing, but if
		you do type-ahead, it will appear,  as soon as you hit
		the key, not when actually used, and the logfile will
		be exactly what you see on your screen.
		Control characters will be echoed literally, except for
		delete, which is processed correctly.

nouline		turns off uline feature (see above)

send=		starts sending a file to the other machine.  The rest of the
		command line is the file name.  What you should do is first
		log on to the machine, and get into an editor with insert mode,
		then type control-A, then issue the send command, and wait
		for a message that it finished.  If you want to abort, type
		another control-A, and issue  the ABORT command.

sync		used to set synchronization character,  The
		synch character is used by the send command
		to make sure that vth doesn't transfer stuff
		too quickly.  vth waits for a synch character
		after sending each line (and the <CR> with it).
		The synch character is initially linefeed,
		which should be okay.  This might not work
		well if you are transfering a file with
		embedded control characters.  (eg. runoff output)

abort		abort file transfer (see above)

close		turns off the logfile, and closes the file.


help		lists this file on your terminal

quit		stops program, before using the quit command it is
		VERY IMPORTANT THAT YOU HANG UP THE PHONE, that
		is done by typing ^q^u^i^t at any time.  After typing
		the ^quit sequence, you must wait for the message
		"NO CONNECTION", and the prompt "BIZCOMP:", then, and only
		then is it safe to type the escape character and issue
		the quit command.  You will get a message "vth termination",
		Between the time you attempt to
		hang up the phone, and the time that the connection is
		actually broken, garbage characters will be put on the
		line in both directions, but that should be okay, because
		you will be logged off by that time.


NOTES:		when you issue the start command, there will be a delay
		before you go into transparent communication with the
		modem.  During that period typeahead is disabled, and
		any characters you typeahead will not be echoed, and will
		be thrown away.


		After going into transparent mode, you will be prompted by
		the bizcomp intelligent modem for a command.  Usefull commands
		include:

		D<phone-number>	=> dials the number, if busy, or no answer,
		it sends the message 'NO CONNECTION' to your terminal.  If
		that happens, either issue another D command, or type the
		the control character, and issue a quit command.
		command.

		R<phone-number> => same as D, except it retries if busy
		or no answer.  Pressing a key will abort either command.
		If no number is given, (ie. R<cr> or d<cr> is typed)
		the last number used will be used again.

		N		=> displays last number used.

		There are several other commands, DO NOT USE THEM!!!!
		THE OTHER COMMANDS COULD CHANGE THE ESCAPE SEQUENCE
		ACCIDENTLY, OR DO OTHER THINGS WHICH COULD RESULT IN
		THE PHONE BEING IMPOSSIBLE TO HANG UP.

		Remember, only issue the quit command if
		the last thing you got before typing the
		escape character was the "BIZCOMP:" prompt.


LESS IMPORTANT COMMANDS:


halfdup		makes vth echo everything you type back to you,
		presumably, for use on a half duplex machine.

fulldup		turns off echoing, true by default when program starts


odd		makes all characters sent to the modem have
		odd parity

even		makes all characters sent to the modem have
		even parity

none		makes all characters sent to the modem have
		zero parity

ones		makes all characters sent to the modem have
		set parity bits

nofill		makes vth swallow fill characters

fill		turns off fill feature (vth never generates fill characters)
