- ABSTRACT: PIP (Plug In Potocols)
-
-
-
- Terminal authors know this problem well. There is always one
- more protocol and there is always one more user who needs (or at
- least wants) it.
-
-
-
- Under DOS external protocols are well known and they integrate
- themselves more or less (mostly less) into the environment of
- the terminalprogram.
-
-
-
- PIP's shall provide this service for ZOC. ZOC provides a
- socket to plug in external protocols. This socket serves as an
- integration basis and lets the plug access important resources
- of the terminal program, mainly the com port and the terminal
- window.
-
-
-
- The ZOC Plug-In-Protocols are not the first attempt to integrate
- external protocols into terminals. On the Amiga exists a
- standard called XPR which has developed from the CIS-B sources
- of General Videotex (at least I believe so).
-
- It is rather a big think, requiring the Terminal program to
- provide services for file access, video access and so on. I
- think that this is not necessary, since unix style file access
- is a well accepted standard and with OS/2 it requires few lines
- of code to open a nice window (either running under PM or VIO).
-
-
-
- Thus the interconnection between the socket (ZOC) and the plug
- was kept as simple as possible. This means of ease of
- implementation for the author of the terminal (me :-) and almost
- zero effort to understand the whole thing for the plug author
- (maybe you).
-
-
-
- If you are having any problems let me know (check the helpfile
- about how to contact me). I will help you as far as I can.
