		   CONTENTS OF SIRIUS MS-DOS DISTRIBUTION
		===========================================

(Based on Columbia University IBM PC Kermit Version 1.20 of 30 November 1984)

SIRIUS.ASM	Source code for Kermit, uncommented and with irrelevant
		conditional assemblies removed. Set up for 256K Sirius with
		I/O Subsystem version 2.5. Includes VT100 subset emulation.
		Generated from KERMIT.SRC using COMPRS.

SIRIUS.SRC	The complete source - ver. 1.20 including IBMPC and Z100 code.

SIRIUS.FIX	EXE file translated into ASCII using KFIX.

SIRFIX.ASM	Translates EXE format file into ASCII using translation
			0 1 2 3 4 5 6 7 8 9 A B C D E F    (Hex) to
			0 1 2 3 4 5 6 7 8 9 : ; < = > ?    (ASCII)
		Identical to that for IBMPC by Daphne Tzoar, CUCCA.

SIRGET.BAS	Bootloader written in Microsoft BASIC. Expects to receive  
	  	file in FIX format from main port and translates it into EXE
		file KERMIT.EXE. Communicates with KERSEND.FOR
		on the mainframe.
		Adapted from version for IBMPC by Daphne Tzoar, CUCCA.

SIREXE.BAS	Translator written in Microsoft BASIC. Takes input from
		KERMIT.FIX and writes to KERMIT.EXE. Used when a new version
		of KERMIT.FIX has been downloaded by KERMIT to obtain the
		EXE file.
		Adapted from version for IBMPC by Daphne Tzoar, CUCCA.

SIRSEND.FOR	FORTRAN-77 mainframe side of boot-loader.
		Adapted from version for IBMPC by Daphne Tzoar, CUCCA.

SIRCMP.FOR	FORTRAN-77 program to compress source programs prior to
		transfer via Kermit. Removes all comments, blank lines and
		all conditional assembly sections except that requested.

			NOTES ON VT100 EMULATION MODE
			=============================

The distributed version of KERMIT is configured with VT100 emulation on by
default. Thus when the CONNECT command is given, the cursor keys are reset,
function keys 1 and 7 are defined to ^]B and ^]C respectively, and the CONT
key made to behave as CONTROL (i.e. the same as ALT). Both the cursor keys
and the numeric keypad can be set and reset by escape sequences from the
mainframe.

These functions require that the location of the key definition table in
RAM be known. Unfortunately, this varies depending on the amount of RAM
installed and also on the version of the I/O subsystem (shown in the disk
boot banner). The current version is for 256K RAM and I/O subsystem versions
2.3 and 2.5. KERMIT.FIX may be edited to allow for other configurations, as
follows.

On line 17, characters 33-36 represent the paragraph address of the key
table. Here this is "913?" which translates to address 3F91H (see note on
translate table above, also note the Intel convention of high order byte
stored second). These four characters must be altered.
---------------------------------------------------------------

	RAM Size	128K	256K	384K	512K

	3?    becomes	 1?	 3?	 5?	 7?	etc.
---------------------------------------------------------------

	I/O Subsys	2.3	2.4	2.5	2.6

	91    becomes	 91	 91	 91	 2:	 
--------------------------------------------------------------
*** A number of these are inferred and untested.  


With regard to incoming contol sequences, these are translated to VT52
sequences where appropriate and passed to the O.S. Where no translation
is possible, the sequence is ignored. Thus some functions are NOT
supported. e.g. 132 column mode, set scrolling limits, most of the set and
reset modes (ESC [ h and ESC [ l), alternate character sets, tab sets and
double height/width characters.
