|Planet MVS TCP/IP on IBM mainframes|
The first working hypertext system was developed at Brown University, by a team led by Andries van Dam. The Hypertext Editing System ran in 128K memory on an IBM/360 mainframe and was funded by IBM, who later sold it to the Houston Manned Spacecraft Center, where it was used to produce documentation for the Apollo space program.Hypertext is the foundation of the World Wide Web (WWW)
Tip: Take the Archive link at the top of the page and look at the February archives which include OS/390 2.5 and 2.6 TCP/IP migration pages. Well worth the clicks!
But I do recommend this book by Donald Alcock: Illustrating C: (Ansi/Iso Version). I also have his book on Pascal. I wish he'd write one on Java. Pick up one of his books at a bookstore and see how well he illustrates examples.The two main C compilers for MVS are:
Using Send or Receive Events, you can look for the Reply code of 226 to come back from the server, which is the standard code that most FTP servers return (the exception we're aware of is an MVS system, which returns a 250).
The code you do not write does not have any bugs!
Contrary to popular belief, OS/390 can be ordered without IBM's TCP/IP
stack. You can choose to
|TCP/IP was not designed to be a robust business-oriented communication protocol. SNA WAS! APPC is a robust business-oriented communications protocol but harder to set up on both ends: Server and Client. TCP/IP is very easy to set up either the Server and the Client hence its popularity.|
Our IBM rep said that our network guy was the first one to get TCP/IP working on MVS in Dallas (and without IBM help which was rare in those days). I remember hearing him over the cubicle wall "I can PING it! I can PING it!". TCP/IP for MVS communicated through the Cisco router on the white floor (which used a Mac Plus for its console).FTPALL001I MVS TCP/IP FTP R1.0.2 FTPALL105I Connecting to 18.104.22.168, port 21 421- |:/:/:/| | | I'm Bart Simpson--who the hell are you? | | | (o)(o) Your machine isn't known to the DNS.
