Amiga Terminal Emulator
Version 0.9, 1-August-1986
Copyright (C) 1986 CompuServe Inc.
By Steve Wilhite & George Jones
1.0 INTRODUCTION
AmigaHost (AHost) is a full featured, terminal emulation
program for the Amiga.
AmigaHost features ANSI terminal emulation, file transfer
with CompuServe's B-Protocol, KERMIT, and XMODEM, file
capture/send, user defineable function keys, a "script"
language, RLE graphics, and a special Conference Mode for
use with CIS.
AmigaHost was designed primaraly for use with CompuServe's
Consumer Information Service (CIS). However, it is well
suited for use in many diverse environments.
AmigaHost may be freely copied and distributed. It may not
be sold or used for profit.
2.0 TERMINAL EMULATION
AmigaHost recognizes ANSI escape sequences by useing the
Amiga's console device. For best Effect with CIS, select
terminal type VT100 (type GO TERMINAL at any "!" prompt).
The baud rate is automaticly set to the rate that was
selected via preferences.
3.0 RUNNING AMIGAHOST
AmigaHost may be run from workbench or CLI. To run from
workbench, double click the AmigaHost icon. To run
AmigaHost from CLI connect to the directory (CD) that
contains AmigaHost and type "ahost". If AmigaHost is copied
to c: typing "ahost" will always run the program.

4.0 FUNCTION KEYS
Each function key may be have up to four definitions stored
for it, so that when you hit the key the text is sent to to
the host computer (the key definitions are actually
scripts).
To define a function key, select "Define Function Key" from
the options menu, then select select "Normal", "Shift",
"Control" or "Alt" (= Amiga Key) from the sub-menu. A
requester will pop up and allow you to enter definitions for
each of the ten function keys. Enter your definitions and
then select "OK".
To execute a function key, simply hit it (or with "Ctrl",
"Alt" or "Shift" as appropriate.
When AmigaHost is exited, the key definitions are saved into
a file called "Softkeys.def". When AmigaHost starts up this
file is read in to set up the initial definitions.
5.0 SCRIPTS
"Scripting" allows you to perform automatic logins,
automaticly capture messages, and perform simple commands.
Here is a sample script that will log in to CompuServe and
capture all the new messages from the AmigaForum and logout.

#e
AmigaHost scripts are implemented with a very simple,
interpreted language. A script consists of text to be sent
to the host computer, mixed with script commands. Script
commands start with a pound sign character, #, which is
followed by one or two characters denoting the specific
command. Some commands take one or more arguments. The
arguments are quoted strings (separated by commas if there
is more than one argument). Any character may be used for
the quoting. The second occurrence of the quote character
terminates the argument.
Scripts may be stored in files or function key. To execute
a script from a file, select "Execute script file" from the
"Options" menu. To execute a script from a function key,
simply define it and press it.
5.1 Script Commands
The following is a list of the script commands supported by
AmigaHost:
#<new-line> "#" at the end of line is ignored.
This allows script files to be
formatted in an visually pleasing
manner.
#! This is introduces a comment. All
characters on a line following "#!"
Page 4
are ignored.
#:'label-name' This introduces a label. Labels
provide reference points in the
script to tell the "go to" and
"case" commands where to go
(implementors comment: I felt like
telling the case and go-to
statements where to go !).
Labels are case sensitive.
#('pattern', 'label' [, 'pattern', 'label']...[,'seconds'])
This is a case statement. The case
statement is begins with "#(", and
is followed by any number of quoted
pattern/label pairs, and optionally
a integer " timeout" value.
If the any of the the patterns are
sent by the host computer, the
script jumps to the corresponding
label and execution resumes there.
If timeout value is specified, and
none of the patterns are seen
within the given number of seconds,
execution resumes following the
case statement.
Patterns are case sensitive. An an
attempt to go to an undefined label
will terminate the script.
#command The text of the argument is
executed as an AmigaDOS command.
Wait for the command to finish.
#e Exits AmigaHost
#g'label' Go to the the specified label.
#i+ "#i+" makes output from the host
computer invisible.
#i- "#i-" makes output from the host
computer visible
(un-invisible).SKIP
#lo'file' Open a logfile and write all
incomming characters to the screen
and the file.
If the file exists text is appended
to the end of the file.
#lc Close the logfile.
Page 5
#p'pattern' Wait unconitionally for the
specified pattern from the host
(dangerous).
#s'file' Execute the specified file as a
sub-script file.
#t'text' Type the specified text to the
screen.
"\c" is translated to Control-"c"
where "c" is any alphabetic
character. "\\" is translated to
"\".
#w'number' Wait for specified number of second
#xp; Start a new CLI (Push to a new
shell). The script proceeds
without waiting for the CLI to
finish.
#z "#z" terminates the current script.
6.0 FILE TRANSFER
AmigaHost supports a variety of file transfer protocols:
6.1
CompuServe B Protocol
B protocol is an error correcting file transfer protocol
developed by CompuServe Inc. to facilitate transfer of
data, programs, text files etc.
Select "B Protocol" when uploading or downloading files from
CompuServe. There are no menu options for B protocol. The
CompuServe's software will cause the Amiga to perform the
upload/download.
If you select file type ASCII (in response to a CompuServe
prompt) the Amiga translates all linefeeds to
carriage-return/linefeed for files that are uploaded (to
CompuServe), and strips all carriage-returns on downloads.
Binary files are transfered "as is".

6.2
XMODEM
XMODEM is a simple protocol developed to allow file transfer
between two (CP/M) micro computers.
To upload/download files with AmigaHost using XMODEM, log in
to the remote computer and initiate a send/receive there,
then select "Send" or "Receive" from the "XMODEM" menu as
appropriate.
You must select either "ASCII" or "Binary" as a sub-item
when performing XMODEM file transfers.
When uploading ASCII files linefeeds are translated to
carriage-return/linefeed. When downloading ASCII files
carriage-returns are striped. Binary files are transfered
"as is".
AmigaHost's XMODEM does not support CRC.

Kermit

6.4
Capture/Send
You may "Capture" text to a file as it comes in the serial
line. To capture text, choose "Open Log File" from the
"File" menu. A requester will appear to allow you to type
the name of a file in which to save all incomming text. To
stop capturing text, choose "Close Log File" (from the
"File" menu).
To send a text file "verbatim" to a remote computer, select
"Send Text File" from the "File" menu.
7.0 RLE GRAPHICS
AmigaHost supports CompuServe's RLE graphics protocol. Type
"GO VID100" at any "!" prompt for selection of RLE pictures.
Page 7
8.0 CONFERENCE MODE
AmigaHost supports a special mode to facilitate use of
CompuServe's Conferencing/CB environment.
The user types his input in one window, and all output is
routed to a second window.
The user may request highlighting of lines containing
specific patterns (such as a person's CB handle, or words of
interest like "disk" or "monitor"). To request
highlighting, choose "Set Pattern" and a highlighting color
from the "CO-Options" menu. A requester will pop up to
allow you to enter the pattern to be highlighted. All
subsequent output lines containing the pattern will be
displayed in the color selected.
Text Capture (logging) may be turned off and on in
conference mode by selecting "Open Logfile" or "Close
Logfile" from the CO-Options menu.
9.0 CAVIAT EMPTOR
AmigaHost always sends 8 bit, no parity data, and strips
parity on data received. XON/XOFF is not enabled.
System requestors appear on the workbench screen. For
example, if a file can not be opened because a disk is write
protected, the message concerning the write protection will
come up behind the AmigaHost screen, both file transfer
windows will be deactivated. To see the requester, type
Left-Amiga-N, to get back to AmigaHost, type Left-Amiga-M.
