The following corrected file replaces the one announced
previously.  It will be in SIMTEL20 at micro:.

DO NOT USE THE ONE PREVIOUSLY ANNOUNCED.  THE ADDRESSES WERE
OFF BY 5 BYTES IN SEVERAL PLACES BECAUSE I HAD AN EARLY COPY OF
MODM700 THAT DID NOT MATCH THE ONE AT SIMTEL20.

;		PAT700V2.ASM

;These patches should be made to MODM700 to obtain the results
;described.  They were previously described as patches to MDM730
;in the file PAT730V8.ASM and were not done in the source code
;for MODM700.  It appears that all of the other patches in PAT730
;were included properly. The object code addresses may have changed
;from MDM730 to MODM700 so use those given below only for MODM700.
;			....    Bob Plouffe   12/28/84

TRUE	 EQU	0FFH
FALSE	 EQU	0

MAXWAIT	 EQU	16		;USE AT LEAST A '5' HERE.
RUB	 EQU	7FH
TERM	 EQU	1618H
MENU	 EQU	32EDH

RUBCON	 EQU	TRUE		;want rubout to go to console?
UNDO$J	 EQU	TRUE		;set to TRUE to restore the 'T'
				;option so that remote end doesn't
				;automatically come up in terminal
				;mode at the end of a file transfer
;*************************************************************
;
;This restores the feature that allows the RUBOUT character to
;go to the console if you desire it.  Code was added in MDM730
;that prevented rubout being sent to console in terminal mode.
;
;In the routine TERML
	ORG	1F0FH
	IF	RUBCON
	DB	0,0,0,0,0	;deletes rubout filter
	ENDIF

	IF	NOT RUBCON
	CPI	RUB
	JZ	TERM
	ENDIF

;***********************************************************
;THIS ONE CONTRIBUTED ANONYMOUSLY AS undo-j.asm AND INCLUDED
;HERE AS AN ADDITIONAL OPTION.
;To undo the 'J' option and restore the 'T' option as it has
;always been. Set UNDO$J to TRUE to enjoy this option.  Irv
;never did change the help screens to describe his 'J' option
;anyhow.  The 'T' option is still the one described there.

;The following code is in the DONETC routine:
	ORG	2AFBH
	IF	UNDO$J
	JNZ	MENU
	ENDIF
	;
	IF	NOT UNDO$J
	JZ	MENU
	ENDIF

; and at the following storage locations near the end of the file.
	ORG	4952H
	IF	UNDO$J
	DB	'T'
	ENDIF
	;
	IF	NOT UNDO$J
	DB	'J'
	ENDIF

	ORG	495FH
	IF	UNDO$J
	DB	'T'
	ENDIF
	;
	IF	NOT UNDO$J
	DB	'J'
	ENDIF

;*******************************************************************
;This patch fixes a bug found by Ron Fowler that causes the wrong
;file to be erased in the directory when overwriting existing files
;in batch mode.
;..in the routine at CKCPM2:
	ORG	2238H
	NOP			;These 2 bytes replace 'CPI  0FFH'
	INR	A

;*******************************************************************
;This patch makes the program MUCH more tolerant of network or
;transmission delays such as found in packet switched nets (ARPANET)
;as well as on satellite communication links.  Do not use a value for
;MAXWAIT less than 5 (5 seconds) and even as high as 16 seconds is ok
;which will then tolerate some of the large throttling delays often
;encountered.
