Re: FTP

Hi, Rob,

Good sleuthing, there, Rob ... :-)    (Your google-fu is strong, today.)


I just remembered that those early versions ran entirely above the MI layer, so they were quite slow. It was all based on and ported from some IBM mainframe TCP/IP stuff that was written in Pascal.  And, if you wanted to write your own code to use TCP/IP on those early versions, you also had to buy the AS/400 Pascal compiler.  And, this was not a "sockets" type of interface, but something much older and more primitive.

I cannot recall at what point IBM re-wrote much of the TCP/IP stack to use the new low-level sockets support that was eventually built into the SLIC kernel, ... I think it was V4R-something?   (Anyone remember?) 


(I am confident that this support was in there by V4R4 ...)


Those were "Fun" times ...

If you then search for "5728-TC1" you find some interesting stuff, like the city of Homestead FL had to pay$17k just for 5728-TC1 on their B50.  (and now it's included, right?)
