NAME
	rcc - interface to the 370/158

SYNOPSIS
	rcc

DESCRIPTION
	rcc is a program which allows communication with the 370.
	When using rcc, your terminal effectively looks like any
	other terminal connected to the 370, with the following
	differences:

	The break key will not interrupt a process while it is going on.

	Several commands are available:
	<DEL> exits from rcc, i.e. it causes a return to UNIX.
	<CTRL-C> copies lines from your Wylbur workspace to rcc.audit, with
		much smaller probability of loss of characters than
		"list" with record mode (see below) on.
	<CTRL-S> sends a UNIX file to Wylbur. Put Wylbur in collect
		mode with a long line length (e.g.,100) first.
	<CTRL-R> starts and stops recording on the UNIX file rcc.audit,
		in the directory from which rcc was called. This is
		useful if you need a record of your transactions with the
		370 (for instance, while using the Arpanet).  However,
		the <CTRL-C> option above is the right way to copy files.
	<CTRL-U> temporarily returns you to UNIX. To return to rcc,
		type <CTRL-D>.
	<CTRL-D> initiates debugging print on dbg.  In this mode, every
		character transmitted by the 370 is written on file dbg.
FILES
	/tmp/rcc.lock	contains the user-id of the current user of
			rcc.
	/dev/ttyg	the terminal line connected to the 370.
	rcc.audit	created when copying from the 370 or in record mode.
	dbg		created when debugging mode is on.

DIAGNOSTICS
	If you are not logged off the 370 (and admit it), rcc will
	not let you exit.

	If the rcc line is in use, an appropriate message will inform
	you who is using it.

BUGS
	Files with lots of tabs get somewhat garbaged on transfer to
	rcc.audit. The following will get you around that:

	COMMAND ? l '_' 	/hunt for character not in Wylbur file
	VOID RANGE		/good, '_' is not in the file
	COMMAND ? ch ' ' '_'	/change all blanks (and tabs) to '_'
	    .
	    .
	    .
	COMMAND ? set page 3	/to avoid losing characters
	COMMAND ? l unn 	/lists the file
	    .
	    .
	   hit appropriate carriage returns to list each 3 lines
	    .
	    .
	    .
	get back to unix

	% ed rcc.audit		/call the UNIX editor
	5656			/# of characters in file signifies ed ready
	1,$g/^$/d		/ed commands to get rid of blank lines
	1,$g/^ /d		/and change '_' back to ' '. Note: gets rid
	1,$s/_/ /g		/of all blank lines.
	w <filename>		/best to save under a differnt name, since
	q			/your next use of rcc will clobber rcc.audit
