Section 12
Modem Play
Modem play is also called "remote Amiga" playing. This means you have the
ability to play a game against your opponent that is seated at another
Amiga, at some remote location. There are two different forms of remote
Amiga:
* Null modem
* Modem
The "Null modem" mode means that two amigas are connected by standard RS232
cables with a "null modem" adapter. The RS232 cables and null modem
adapters are all standard equipment available at your Amiga store. The
null modem mode eliminates the necessity of using a telephone line, but
limits the distance between the two Amigas to the length of the cable. If
you have two Amigas in the same room or house, the null modem is a good way
to play remote Amiga games.
If you want to play with a friend across town or across the country, the
modem mode is required. The modem mode means that each Amiga is connected
to a modem device with a standard Amiga modem cable. Head Coach supports
Hayes compatable modems.
The null modem may be used at speeds up to 19,200 baud (1920 characters per
second). When used with a modem, speeds are limited by the modem being
used.
Starting a Remote Amiga Game
When you begin a Head Coach game, Head Coach asks if you are starting up a
remote Amiga game; click the "Yes" box. Head Coach then begins the process
of establishing the communication between the two Amiga computers. Head
Coach first needs to know if you are starting up a null modem or a modem
game. Enter either "N" or "M", as instructed.
Head Coach then directs you through a series of questions that will enable
Head Coach to establish communication. Before beginning a remote Amiga
game, you and your opponent must decide:
* Which mode to use (null modem or modem)
* Baud rate to use (you are given a list of choices)
* Which team will do the calling
(The other team will answer)
* Which team is home team and which
team is the visiting team
After answering the questions, if you are in the modem mode, the calling
computer will place a call to the answering computer (during the dialog,
you have already typed in the telephone number of the receiving computer).
The calling computer will send a special message to the answering computer,
and await a special response. If the answering computer does not answer in
one minute, the calling computer will repeat the request.
After the communication has been synchronized, starting the game continues
normally. When a team file is needed, the file is taken from the computer
for that team (either home or visitor) and is sent to the remote Amiga. In
this manner, it is not necessary for each computer to have the files of the
opponent team.
The home team computer will provide the weather and random number. At this
point each player sees a normal Head Coach game, with responses for the
opponent being taken from the remote Amiga and transmitted to the local
Amiga computer. Each player will see the notice "Waiting..." when the
local computer is waiting for the remote player to provide some
information.
The communications processing in Head Coach is sophisticated. All data is
transmitted in small units, with check information transmitted. If a
transmission is bad, due to line noise for example, the transmission will
be retried. Furthermore, at the beginning of each play, the down,
distance, game time, and score is compared between the two computers. This
guarantees that the two computers remain fully synchronized.
