UUCP - UNIX to UNIX protocol.  Used for receiving batch news
and mail from the Internet

X.25  An economical network used to give local presence to
a national networks.  ( Compuserve for example uses an X.25
network to give local access all across the US)

ISDN  A new way of sharing voice and high speed data
transmissions on the same line.  Very popular in Europe and
expanding use in the US.

SLIP  -  SLIP stands for Serial Line Internet Protocol.
SLIP is a "non-standard" for framing IP packets and shipping
them over a serial line (e.g. a cable, or a pair of modems),
thus allowing a home machine to dial up and become part of the
Internet. Effectively, SLIP turns a serial port into a logical
ethernet port.

Many workstations and terminal servers can support SLIP.
On the Macintosh side, several vendors offer SLIP modules
forMacTCP. Macintosh software which communicates with the
outside world via MacTCP will continue to work over SLIP,albeit
somewhat more slowly due to the relatively low bandwidth of
modem connections.

CSLIP  -  CSLIP stands for Compressed SLIP.  CSLIP reduces
the size of the headers in IP packets by eliminating a certain
amount of redundancy.  This improves interactive performance.

PPP  -  PPP stands for Point-to-Point Protocol.  PPP can
support both synchronous and asynchronous connections and
protocols that are not IP-based (such as AppleTalk). It
provides specifications for error correction, feature
negotiation, escaping control characters, etc.  PPP is becoming
more and more popular, especially as MacPPP, a MacTCP extension
available via anonymous FTP from merit.edu in pub/ppp, has
matured into a stable and viable alternative to the various
available MacTCP SLIP LAPs.   Although SLIP continues to be
more prevalent than PPP, PPP is likely to become more popular
in the future.

[7.3.05] - Setting up a high speed Macintosh Network on the Internet.

Required items for this implementation:

1.  MacTCP (or equivalent)
2.  Network Cabling and Software (10 Base T Etherwave recommended)
3.  Internet connection (T-1 , though 57K or 14.4 Slip will do.)
4.  Router, CSU, and DSU for direct connection (can be rented).
5.  Modem (14.4 or better preferred) for dial up slip connection.
6.  Server software and/or client software for Internet access.

There are two limitations on any use of Internet.  One set
from your system, and another set from any other system you
work with.  The closer any system is to the Internet's main
backbone(s), the faster access to it is, and the smaller the
chance of non-delivery of any packet.  Other factors are,
Telnetable or not, FTPable or not, Gopher server or not, WAIS
or not, and many more.  You must keep in mind what kind of
people will be connecting to the Internet through you, and what
kind of people will be connecting to you through the Internet.
Is your information valuable, or is your information something
people can have for free?  Do you feel safe without good
security, or do you need something in the lines of a firewall?
All these things can limit your services.  Do not think that
all limitations are bad though, many are required tokeep your
service viable.

Once you have decided what you would like your server to do, it
is time to pick the software.  There are many different
applications that provide many different services. Some of the
things that are very important in all software are:

1) The ability to directly connect to Internet (no add ons).
2) The ability to handle long messages.( above 32k)  There
may not be too many, but its the important one that is that will
get you every time.

A strong commitment from the developers to continue to develop
the software along multi-purpose lines for Internet use.

7.4 - Modems and a Macintosh BBS
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

[7.4.01] - Modems

Because of the Macintosh's closed box design for
most Mac's the most common modem is an external modem.

See section: 14.06 - Carrier Dedected for a list of modem
companies.

-------------------------------------------------------------------
[7.4.02] - Carrier detect and the Macintosh

Carrier detect allows your program to determine when a caller
is still connected to your server.  If the connection is
un-expectantly broken, your software should immediately reset
the modem and wait for the next call.  Early Macs, 128, 512k,
Mac Plus, LC, LCII, MacIIvx, some Performas, , Powerbook 100,
have no carrier detect pin in their serial ports.  Newer Macs
all have this implemented.  Your BBS should allays use Carrier
Detect cables in order to make sure that this important
function works.

--------------------------------------------------------------------
[7.4.03] - Hardware handshaking and the Macintosh

Hardware handshaking is a system whereby the Macintosh and
modem ensure that no data is lost.  If a Macintoshes internal
buffer of data becomes full it asserts a DTR line telling the
modem to stop transmitting.  Your cables must support hardware
handshaking as well as Carrier detect.

Your standard modem cables may not have carrier detect and
hardware handshaking capabilities built in.  Most cables
shipped with modems do NOT have these capabilities, as do most
mail order cables.  If you can buy your cable from your BBS
software supplier, you should.

---------------------------------------------------------------------
[7.4.04] - High speed modems

With the advent of high speed modem capable of 230,400 baud
with compression, can my Mac handle them?

Sure, you should make sure that your software has a modem
driverfor your particular 28k modem.  Also make sure you are
using a high speed serial Nubus card couple with a high speed
hardware handshaking and carrier detect cable.  Or you can use
an Ethernet connection to the Internet.

The Macintosh will handle any v.fast or v.34 modem with no
problem, but realize that the standard is not complete (as of
8/94) and that the modem purchased with a v.fast chip will have
to be upgraded to a v.34 standard later - though some modem
manufacturers are offering FREE upgrades.

With the cost being within $50 per modem of a 14.4 all sysops
should consider buying only 28k modems because of the speed
difference it will offer callers, and the time that it will
free up your BBS for more callers by allowing faster downloads.

--------------------------------------------------------------------
[7.4.05] - Special pricing on modems for SYSOPS.

Read any of the Magazines mentioned at the end of this FAQ and
they will have charts showing the latest special ( cheaper?)
pricing for Sysops from modem manufacturers.  I have found that
your local giant electronic discounter may have better prices
than the manufacturer offers today.

[7.5.02] - First Class 2.5

FirstClass is a multi-platform communications system that
integratesfull fledged e-mail with workgroup communication
servicesQand offers the same ease of use, functionality and
high performance over network or modem.

One FirstClass server combines the following application
functionality in one integrated system:

      Complete office electronic mail
      Network conferencing for electronic discussions
      Remote-access or network bulletin board system (BBS)
      Conferencing
      Multi-Platform & Language Support

Of course one of the primary reasons to use FirstClass as an
on-line system lies in the strength of its multitasking
graphical interface. Modem access is efficient and permits
background transfer of files (in both directions
simultaneously) even while reading mail, chatting or using
other system features.

FirstClass as a BBS , has the ability to access and search
CD-ROMS or other volumes on-line is very useful, as is the
ability to send mail to any user or conference the BBS user has
permission to.  Administrators may accurately track what users
have uploaded or downloaded what through statistics and billing
features.  They can create custom icons and background
pictures.  Accommodate users of any computer type through a
command-line interface to FirstClass similar to the shell
if they call with a VT100 compatible terminal.
