- I have just participated in a project, that I thought I would tell you about. If
- you have no interest in IBM's AS/400, then just hit the delete button and go on
- to the next mail message.
-
- The problem at hand was that a VAX/VMS system had been installed in a pure
- AS/400 shop. The AS/400 users needed access to the VAX, and print and files
- needed to to be transfered back to AS/400 land.
-
- There are available on the market products that enable VMS and AS/400 to talk to
- each either on one or the other's terms, but in the interest of 'openness' I
- recommended that we investigate TCP/IP as the common factor.
-
- On the VAX/VMS side, that was easy, as you will know since you are reding this
- list ;-).
-
- On the IBM side, we found two TCP/IP alternatives, IBM's and OCS fra Open
- Connect Systems. IBMs was quickly dumped, because they did not have a VT
- emulator in their product (e.i. it was only dumb TTY emulation).
-
- The OCS product set consists of a box (an OCS server) that connects to the
- Ethernet on one side and to Token Ring on the other side. On the Ethernet side
- it acts as an IP node, on the Token ring side it acts as an APPN node. This
- functionality is also available as code to run sn either an RS/6000 or a Sun,
- but we went with the box in this case.
-
- In addidtion to this, some software is needed on the AS/400, in this case a
- Telnet client and an FTP Server.
-
- On the day of the installation, I arrived with my Multinet kit and the OCS-guys
- with their box and software.
-
- By the time I had Multinet up and running on the VAX, I could PING the OCS box.
- And after watching a lot of AS/400 screens flick by we where also able to FTP
- from the VAX and Telnet from the AS/400.
-
- Most of the work went in to getting the correct translation tables installed to
- convert from DEC Multinational Characterset to Danish Multinational EBCDIC and
- vice versa. This for all components, Telnet, FTP and print and in both
- directions.
-
- After all that was done, it worked like a dream.
-
- Telnet to the VAX works fine, if you get used to running 'emulated full duplex'
- on a block mode terminal.
-
- FTP between systems works, with a fine mapping between the 'unix-style' file
- system assumed by FTP and the 'library/file/member' structure on the AS/400.
-
- Print from the VAX to the AS/400 printers is done by FTP-ing the print file to a
- special file on the AS/400, that turns out to be the spooler. Support is
- available for both 'pure' ASCII as well as Fortran Carriage Control.
-
- All in all everyone was very pleased about the result, and it certainly isn't
- the last time I will recommed a solution like this one.
-
- If you have any questions, please post them to me. I am NOT an AS700 expert (not
- even a user), but I will try to answer your questions or pass them on to someone
- who can.

- Regards
