Test Request aids in diagnosing 5250 sessions.
I've used it with 5294s and other 5250 emulators though
I don't know much about AS400 personally.
It is defined in RFC 1205.
>From a sign on screen, but not signed on you send
0x00,0x02,0x00,0x00 four bytes I believe in one packet.
That 02 is test req bit on.
There is confusion over the first byte, message length.
There may be cases where it must be 0x04.
Now for how tn5250 works.
First, without looking at source:
1: Do all keypress events, unless they are grabbed as a local function,
result in a send to the AS400?
2. Do they automatically go thru the asciitoebcdic translations?
3. Is there a hook for sending a binary string?
Or, if I need to goto the source, could anyone give a clue where to watch
events (strings) and take a send kind of action?
*** what i want to effect is to map a string to probably the escape key to do
testreq.
Thanks a lot. I know i'm a lot of trouble but this stuff is fun. sort of.
