Re: executing datastream commands


i got a BDE station which connects over tn5250 (tn5250_b0-16) to an AS/400. The OS of the BDE is LINUX. There is (for example) a hardware counter connected to the BDE over the V.24/RS232 interface. 

Can you tell me what a BDE is?

I did a search for "BDE" and got back Banco de Espana and Borland Database Engine. Neither of which seems to fit what you're talking about.


Now i am searching/fetching informations on sending datastreams to the tn5250 emu, to initiate an (read-)action on the connected devices to get e.g. the counter value. The value should be inserted into a field on the tn5250 screen like a manual input. Another example is to get a datastream from the AS/400 to play a sound(file).

Are you sure you want to use 5250 emulation for this? Wouldn't it make a lot more sense to have a separate application on the Linux box that sends data from connected devices to the iSeries, and receives sound files to play, etc?

If you modified TN5250 to do this, you'd have an application that would only work with a customized version of one emulator. That would both prevent you from updating TN5250 to get bug fixes, and from ever switching to a different emulator.


Is there already an implemented function/option to do this?

Has anybody got experiences with such a function?

If this is not already implemented, any ideas on how to doing this, writing an external prog or putting this functionality into the tn5250?

Since I don't know what a BDE is or what types of attached devices you need to access, it's hard to answer these questions.
