- 10.1 Introduction
-
- Doors are separate programs that can communicate with the BBS. They
- come in many forms, games, utilities, ect, and can be found on many BBS's.
- It is not guaranteed that all doors will work on 4D-BBS. They may have
- been written for another BBS and may not be fully compatable.
-
-
- 10.1.1 Types
-
- On 4D you can run three types of Door programs.
-
- 1: ARexx
- 2: Paragon
- 3: Cli (StdIO/FIFO)
-
-
- 10.1.2 ARexx Doors
-
- In the cfg_ed you can set up the port name you wish to use for your
- ARexx port. The default is '4D-BBS'. If you run a multi-line BBS, 4D-BBS
- will automatically add a number to the end of your port name.
-
- For Example:
-
- line 0: Port Name '4D-BBS'
- line 1: " " '4D-BBS1'
-
- For specific ARexx commands see the Appendix A3.
-
- Usually all that is required for a ARexx door to run on 4D-BBS is to
- change the address to the ARexx port name. Or also you can pass it the
- ARexx port name as an argument by using 4D-BBS's embedded instructional
- code for the ARexx port name. ^]WT%. This will require a good
- understanding of ARexx if the script is not set up to handle this. You can
- find an example of this in 4DWhosOn.Rexx
-
- Below is a simple menu example on how to start a ARexx door:
-
- H:c A Path/filename.rexx
-
- H is the keypress
- c is for door
- A is the type of door (A,P,O,F)
-
- Note: see menu options
-
-
- 10.1.3 Paragon Door Types
-
- Usually installing a Paragon door is very simple. You have to
- have a directory devoted to doors and assign DOORS: to it. Many doors
- require that subdirectories be set up for them (you will have to read their
- docs about this).
-
- 4D-BBS has two ways to run a Paragon door. The best way is to use
- the door option of 'P'. 4D-BBS will check to make sure the door opens a
- reply port to prevent the BBS from hanging in the door mode. If the reply
- port can not be found 4D-BBS will return.
-
- A simple menu example:
-
- h:c P Doors:filename
-
- The other way to run a Paragon type door is to use the door option
- of 'O'. Some Paragon doors will not work using the 'P' option because they
- don't open a properly names reply port. 4D-BBS will not check for a reply
- port and start waiting for commands with the door option of 'O'.
-
- A simple menu example:
-
- h:c O Doors:filename
-
-
- 10.1.4 CLI (FIFO)
-
- To use this option you must have Matt Dillion's FIFO. It is in the
- public domain. You need fifo.library in your libs: directory and also run
- the fifo-handler. Read the docs that come with fifo for more details.
- FIFO is available at 4D-BBS support BBS.
-
- Any program that does not detach its self from the stdin & stdout or
- open a window should be able to be ran with this option. Ususally if it
- will run on a CLI (with output to the cli) it will work here. Example:
- 4D-BBS editors could be ran as a fifo door! If a user hangs up during a
- FIFO door, 4D-BBS will send a ctrl-C to try to abort the program. It is
- suggested that you only run programs that will abort on a ctrl-c.
-
- A simple menu example:
-
- h:c F path/filename
-
- or with embedded instructional code (EIC)
-
- h:c F doors:h&s/HSclient -t^[P7% "^[P3%"
- the ^[P7% being time left on BBS & ^[P3% is the users name. Use quotes
- around any EIC that may have a space.
-
- There is also a built in SHELL you can start with this option. This
- works VERY well for remote access. But WARNING!! keep it out of the reach
- of users. It is just like using the cli, except you can not click
- requesters.
-
- To run the SHELL use '4D-SHELL'. It is Case sensitive.
-
- example: s:c F 4D-SHELL
