In this presentation from OzKFest 2015, I contemplate various methods to connect an Apple II host running a BBS to the internet for others to 'call' without the need for a modem.
I describe the Lantronix UDS100 serial server device and how I configured it to connect a physical Apple IIgs to the internet and show how to connect to it from an emulated Apple IIgs.

Putting an Apple IIgs BBS on the internet

BBS on the Internet

2. Why?
At the last OzKFest I demonstrated Sean Craig’s
The Complex BBS host system and explained all
the fun some of us had been having online in the
late 80s and early 90s.
There was some interest in the audience for trying it
out, but nobody really wants to use a modem any
more.
An internet connected host avoids the modem.
3. How?
There were two ways forward that I saw:
1) Re-write the game to have an ethernet driver
2) Connect the serial port to ethernet
4. How 2?
There are a few methods of connecting a serial host
to the internet.
1)Using a Serial Port server device to bridge serial to
ethernet.
2)Port redirection on a computer that also has
ethernet.
5. Serial Port Server
Allows serial devices to connect and communicate
over Ethernet networks using the IP protocol family
Could be used to tunnel serial signals
May support several serial port types:
RS-232, RS-422/485
One or more serial ports
An Internet user can connect to the serial port
using Telnet to a dedicated IP address and port
number.
6. Serial Port Server options
I found reference in Comp.Sys.Apple2 for a couple of
options that others had tried.
•Moxa Technologies NPort Server
•Lantronix UDS 10/100/xxxx device server
•Ominously, both had cries for help with the cabling and don’t seem
to be used for Apple II BBS systems any more.
7. Lantronix UDS100
I bought a UDS100 device which has one serial port.
Needs a modem cable (not null-modem)
Pro
Has a disconnect option that recognises a closed Telnet
session and drops DCD so host can reset itself.
Issues modem responses (OK, CONNET 9600, NO CARRIER)
Cons
Must be configured through a connection to the device
(serial, telnet, web server)
Has configuration options that are set in binary.
8. Moxa NPort Server
I bought a DE-302 device that supports two serial ports.
Needs a null modem cable
Pro
LCD screen and buttons on the device allow direct
configuration of the unit.
Con
The manual devotes many pages to the Windows
configuration program and not enough to the actual
configuration settings.
A closed telnet session may not trigger host reset.*
No Modem-like responses.*
*I will be happy to be proven wrong. Please help!
9. BBS Host setup
The Complex host system was written in a way that
relies on modem responses.
The Lantronix UDS100 is well suited for this.
Cable connections (mini-din 8 to db25) are:
1 Hsko – 5 CTS 4 GND – 7 GND 7 GPi – 8 DCD
2 Hski – 4 RTS 5 Rx – 2 Tx 8 Rx+ – no
3 Tx – 3 Rx 6 Tx+ – 7 GND connection
10. BBS Host setup – UDS 100
Channel Settings:
Baudrate - 9600
I/F Mode - 4C (RS-232C, 8-bit, no parity, 1 stop bit)
Flow - 02 (RTS/CTS)
Port Number - 6502
Connect Mode - D6 (full verbose with echo)
Remote IP Address - Leave as 0's
Remote Port - Leave as 0
DisConnMode - 80
FlushMode - F7
DisConnTime - 00:00 (disabled) – or perhaps 5:00
SendChar 1 - 0
SendChar 2 - 0
13. Server needs a Client
The host supports a graphic display.
How to connect to the host to display the graphics?
Spectrum communications software
•Serial and Telnet connections
•Online Displays: ANSI, ProTerm Special Emulation
(PTSE), VT100, The Complex
Dedicated Client software for IIgs, Mac, PC
Is there an Emulator that supports a modem?
Can it connect over TCP/IP?
14. GSport modem emulation 1
When client software sends ATDT to the modem
port, GSport tries to establish a network
connection to a domain or an IP address e.g.
ATDTcrazyworldbbs.no-ip.org
ATDT75.145.20.97
By default this is a Telnet connection to port 23
GSport versions 0.32c and above now support the
provision of a port number to connect to e.g.
ATDTboycot.no-ip.com,9999
ATDT192.168.1.21,6502
15. GSport modem emulation 2
GSport configuration (F4 key)
Serial port configuration
Configuration for the modem port
16. GSport modem emulation 3
When a connection is established GSport sends a
connect message to the host to advise what
connection speed has been established e.g.
‘CONNECT 9600’
Currently, the 9600 is hardcoded and could mislead
clients and hosts if the rate is set differently. A
feature request has been created to have the speed
reflect the client port setting.
17. GSport Client Software
Start with the GSport Internet Starter Kit image
Install Spectrum
Install The Complex Online Display driver
Spectrum/Add.Ons/OnlineDisplays
Start Spectrum and
setup a new phone book
entry that uses
“The Complex” display
Beware: Spectrum dislikes
domain names within the number.
Ewen is already on the case!

Hinweis der Redaktion
Sean did release the source code to The Complex III, so adding an ethernet driver could be possible.
But I wanted the easy(?) option.
I didn’t want to use another computer, so I had a look at Serial Port servers.
Perhaps I can run two host systems?
The Complex III host looks for ‘RING’ and then sends an ‘ATA’ to answer the phone and then looks for ‘CONNECT <speed>’ to confirm a connection.
I am using my old high speed modem cable to connect to the UDS100 from the Apple IIgs serial port.
Refer to the “HOWTO Lantronix & C64” resource for a detailed explanation of settings.
GSPort is an Apple IIgs emulator
It can be downloaded from here:

Unfortunately, BoycoT BBS is no longer active due to lack of interest.The SYSOP, Terry Olsen, received a lot of one time users when he promoted it, but very few repeat calls.

Unfortunately, at the time of the presentation I had not had success in running client software for The Complex within GSport. Investigation continues and may require improvements to the GSport emulator and/or patches to the client software.
The demonstration consisted of
Showing the Lantronix configuration options
Showing how the Lantronix responded to modem commands
Connecting GSport running Spectrum to a real Iigs via the Lantronix device also running Spectrum
If you have a dynamic IP address assigned by your ISP, then you will appreciate a service such as NO-IP.COM which allows you to give out a static domain name for others to use instead of an IP address that will change over time.
