aux-emacs

Short:        Memacs modified to also work off Aux:
Architecture: m68k-amigaos

27-May-92 -- Lance Tagliapietra -- Aux-Emacs 1.0

This  version  of  Microemacs  was  originally  ported  by David Conroy and
released  on  Fred  Fish disk #2.  I have modified it to be compilable with
the ZC compiler from Fred Fish disk #314.  It is also modified to work with
the  AuxHandler  from  Fred Fish disk #79.  When a terminal is connected to
the serial port, the command
	NEWCLI AUX:
or
	NEWSHELL AUX:
will  start  a  cli  session  to the terminal.  Running microemacs with the
command
	EMACS
from  the  terminal  will  start emacs using the Aux:  device for input and
output.  From a CLI window or SHELL window, run microemacs with the command
	RUN EMACS
Microemacs  will then open a window and use the keyboard and video display.
It  is  very important that microemacs be started with the RUN command when
working  in  the  windowed  enviroment.   Failure  to  do  so will create a
microemacs  process  that  cannot  be aborted as control characters will be
eaten by the console.

See the files ME.DOC and WALLCHART for a listing of microemacs commands.

The  modifications  use  the Fish released aux-handler for the serial port.
The  serial parameters are taken from preferences when the serial.device is
opened  with  the  newshell  or  newcli  command.  When emacs is run to the
serial  port,  the  aux-handler is put into "raw" mode.  The aux-handler is
restored to console mode when emacs is exiting.

All  commands  in me.doc work as expected.  Spawning a new cli when running
through  Aux:   puts  that driver back into console mode and the CLI prompt
appears at the bottom of the screen.  Entering the command ENDCLI from this
CLI will resume the editing session where it was left off.

NOTE:   The  run  command  in  a  subjob  (CTRL-X !) has been disabled when
working  from  the  Aux:  cli.  This should not be a problem as the spawn a
new cli command (CTRL-C) works correctly.

The  modification  to  the  source  for  compiling with the ZC compiler was
mostly trivial.  The #if statments for the different systems supported were
changed  to  #ifdef  statements.   Several small syntactic corrections were
made,  most  notably  where the TERM structure is initialized in ANSI.c and
VT52.c.

The  modifications  to  work  with the Aux:  port were made in termio.c and
spawn.c.   The  changes  first  determine if emacs was started with the RUN
command  or  not  and  then  open  a  window  or  initialize the Aux:  port
accordingly.

The  executable  supplied  is  compiled  for ANSI mode.  To use VT52 screen
codes,  set  the  VT52  #define to 1 in ED.H and set the ANSI #define to 0.
The executable created is 2k smaller than the version originally suppled.

Enjoy.
