A Quick Reference
CONEX VERSION 6.3a
Fri 01-28-94 10:34:51
Copyright (C) 1991-94 Erhard Hilbig
CONEX (Latin connection) is used to communicate between IBM personal
computer and a host or between two IBM PCs.
These are the highlights of the program:
- The IBM PC can be used as terminal via COM1 - COM4, via Interrupt 14,
DECNET LAT, FTP TCP/IP, B&W TCP/IP, 3COM (BAPI) at a host.
- COM parameters like baudrate (50-115200), parity, full/half duplex,
xon/xoff or hardware handshake can be set in CONEX.
- Files can be transferred without protocol, e.g., to save a session to
disk.
- Several DOS commands can be used inside CONEX, such as "cd", "del"
or a DOS shell can be entered.
- All incoming characters can be sent to a printer.
- You can transfer files to and from the host via KERMIT protocol
using long packets and sliding windows.
- Tektronix 4010/4014/4105 and DEC VT100 - VT320 can be emulated. The
crosshair in GIN mode can be moved by a mouse.
- Graphical output can be displayed on a HPGL plotter or transferred to
other programs.
- Supports screen modes with up to 50 lines and 132 columns.
- Up to 20-30 pages of screen output can be scrolled back to screen and
edited.
- All keys including the numerical keypad and mouse buttons can be
programmed.
- Incoming characters from the port can be remapped by the user.
- Supports a phonebook
- The configuration of CONEX can be saved to an ASCII file, which can
be protected by a password or CONEX can be patched by itself.
- Several sessions, especially net sessions, can be opened concurrently.
- CONEX is completely written in assembler and therefore very quick
and small. The only file necessary to run CONEX is "conex.exe".
╒══════════════════════════════════════════════════════════════════════╕
│ How to start CONEX │
╘══════════════════════════════════════════════════════════════════════╛
Simply start CONEX version 6.3a with
conex [<number>|<host>] [options]
parameters
───────────────────────────────────────────────────────────────────────
<number> - enter session 0 - 9 (default: 0)
<host> - connect to host in a network
Case 1: Session <host> has been defined previously with <Alt-I>
--> change to this session
Case 2: Session <host> is undefined
--> select the lowest session with empty host name
or session 0, if none available.
port is determined automatically (can be set with <Alt-Y>)
options
───────────────────────────────────────────────────────────────────────
/i<filename> - load different ini file (default: conex.ini)
╒══════════════════════════════════════════════════════════════════════╕
│ DOS Commands │
╘══════════════════════════════════════════════════════════════════════╛
DOS commands can be executed nearly at any time using the alternate keys.
=> <Alt-C> - Change to another drive/directory
You can change to a new drive by adding "<drive>:" to your pathname.
=> <Alt-E> - Erase file
Wild cards cannot be used when entering the filename, but you can
switch to a selection menu with <Page up>/<Page down>.
=> <Alt-X> - eXecute DOS commands
Any valid DOS commands can be executed. But if you want to enter the
DOS shell completely give <Return>. You return to CONEX with "exit".
╒══════════════════════════════════════════════════════════════════════╕
│ Port Parameters │
╘══════════════════════════════════════════════════════════════════════╛
=> <Alt-I> - Initialize connection
The following parameters can be modified
Host: Name of the host to which you are connected. It is only
important if you are working on a network with LAT,
PC/TCP, BW/TCP or 3COM (BAPI). Changing this parameter
will automatically close the old session.
Port: Com, interrupt 14, LAT, PC/TCP, BW/TCP, 3COM (BAPI)
Bits/parity:7 space, 7 even, 7 odd, 7 mark, 8 odd, 8 even, 8 none
Duplex: half - all entered characters are immediately displayed.
full - the host echoes all received characters.
more ...: This allows you to change more parameters which are less
important. These are:
Prompt: You can enter part of the prompt of the connected machine
here. When you enter "return" in "edit mode" all
characters following this prompt are transmitted.
Answer: This string is transmitted, if the host sends ENQ
(decimal 5).
COM PORT and INT 14
────────────────────────────────────────────────────────────────────────
Portnumber: 1, 2, 3, 4
COM1 ... COM4 if they exist. COM3 and COM4 can only be
used if they are defined in BIOS, otherwise you have
to set IO-ports and interrupts for these ports in
conex.ini. (See tech.ref for more details)
Baudrate: 50, 75, 150, 200, 300, 600, 1200, 1800, 2400, 3600, 4800,
9600, 14400, 19200, 38400, 57600, 115200 bits/second
Shows the speed at which characters are transmitted.
Stopbits: 1, 2 - Number of stop bits that follow the end of a
character on a serial line. Normally this has not much
influence on a transmission.
Handshake: none - no handshake
hardware - Characters are only transmitted if pins CTS or
DSR are set (not with Int14).
xon/xoff - XOFF=^S stops transmission
XON=^Q starts transmission again
Normally CONEX accesses the hardware of COM ports directly, because
this more flexible. But you can also set to "Int14" to use the BIOS
interrupt 14. Some network software also use this interrupt.
PC/TCP and BW/TCP
────────────────────────────────────────────────────────────────────────
Telnet port: Default port is 23, some hosts use different ports for
special purposes.
Telnet timeout: How long do we wait for an answer during initial
connection in milliseconds? This value may be increased
for long distance connections.
LAT (Local Area Transport) is used to connect PC and host via
DECNET. A resident program called "lat" must be loaded before using
this option. LAT is contained in DECnet-DOS which is available from
DEC (Digital Equipment Corporation). This software has been tested
with DECnet-DOS version 2.1.
With PC/TCP you can make a telnet connection on ethernet. The PC/TCP
kernel ("ethdrv") from FTP Software Inc. must be loaded before, it is
not public domain. The program has been tested with version 2.04, 2.05
2.11 and 2.2. PC/TCP is a registered trademark of
FTP software, Inc. anonymous file server

BW/TCP has the same features as PC/TCP. The internet number can be
entered directly as hostname or the hostname can be resolved with a
host file. Enter its location in <Alt-Y>. Hostname resolution with a
name server is not supported.
BW/TCP is a product from Beame & Whiteside Software Ltd.

3COM (BAPI)
────────────────────────────────────────────────────────────────────────
CONEX supports BAPI (Bridge Application Program Interface) from 3COM.
You must enter a host name.
