- Introduction:
- ~~~~~~~~~~~~
-
- The ModemLink device was written in an attempt to make modem linkable
- games easier to write on the Amiga. We've seen hundreds of games on the
- PC with modem play capabilities, but most Amiga games don't provide this
- option. This frustrates many Amiga game players, as everyone knows it's
- much more fun to kill your friends then stupid computer-AI people!
-
- It's no secret that most Amiga programmers are not part of some rich
- company. Therefore, it's easy to understand why many developers don't add
- modem play to their games.
-
- First of all, you may be adding a few months to development time just for
- the modem link part of the game. For many hobby programmers, they'd rather
- just finish the game quickly, and move onto new and exciting things. The
- ModemLink device gives the developer all the code required for a basic
- modem playable game, therefore saving on development time.
-
- Another problem is that you'd need two Amigas, with a modem on each, and
- preferably two phone lines (although you could always use a null modem as
- well). Not everyone can have this kind of set up. The ModemLink device
- makes it a little easier to develope the modem linkable game, since there's
- less to worry about. You'll still need to test, but it's the sort of thing
- a friend with an Amiga and a modem can help out with. Since the ModemLink
- device has been tested, and is known to work, a game developer only needs to
- worry about how to interface with the ModemLink device.
-
- Well, this is all very cool and all, but how does it work??? Although I
- don't want to get into the finer details of the device, this is a good
- place to give a rough description of the thing.
-
- The ModemLink device provides two important functions; Modem Connectivity
- and a Reliable Serial Protocol. What does this mean???
-
- Modem Connectivity:
- ~~~~~~~~~~~~~~~~~~
-
- The ModemLink device provides standard routines to dial/answer calls.
- These routines can be used to easily set up a modem connection. They have
- been designed to be very flexible and provide significant control to the
- programmer.
-
- Reliable Serial Protocol:
- ~~~~~~~~~~~~~~~~~~~~~~~~
-
- Once a modem connection is made, data must be sent and received across the
- phone line. One needs to be sure that the data received is correct, and
- the data sent has been received. To do this, some kind of protocol must
- be used, which the ModemLink device provides. Although designed to support
- more protocols in the future, it currently only supports a single protocol
- based on what is called the Stop And Wait protocol.
-
- Anyway, as you might have guessed, the main point to this entire project
- is to make it easier for Amiga programmers to make modem linkable games. I
- offer this package (with source included) free for everyone to use.

- Release History:
- ~~~~~~~~~~~~~~~
-
- R1.2 V36.2 (Oct 26 1997):
- - ModemLink.device would not create the ModemLink Semaphore which is needed
- to make sure that only one instance of modemlink.device is running for a
- given Unit. This has been fixed.
-
-
- R1.1 V36.1 (Oct 25 1997):
- - SendModemCMD now checks to see if modem is OFF only if issued command is
- never echoed back from modem. This is to be compatible with newer
- modems which auto power-up when first command is issued.
- - Cleaned up some documentation.
- - Changed the scoptions file so that it now sets PARAMS=BOTH. It will now
- use both registers AND stack for parameters.
- - Added StormC pragma file in include/StormC_pragmas.
-
-
- R1.0 V36.0 (May 10 1997):
- - Initial release
-
-
- R0.0 V00.0 (July 4, 1996):
- - Modemlink Project begins
