Re: [MI400] 5250 graphics

["Steve Richter" <srichter@xxxxxxxxxxxxx>]

Simon,

Thank you for the info.

I notice that the graphics orders are documented in the older 5250 functions
reference manual, but not in the newer 5494 functions reference. ( instead,
in the 5494 version, a lot of paper and time of the reader is spent on
programmable mouse support that does nothing usefull at all. )

I contacted MochaSoft and they said they dont do 5292-2 and dont plan to in
the future.

And CAE does not have an option for device type.

So I will just file this in the "I just dont get it" file.

I am aware that the crowd says graphics are to be done on a web page, but
the data stream supports the graphics orders that could display say a bar
chart on a terminal, and tn5250 gives the as400 pgm access to a windows pc
which has all the equivalent graphics instructions built into the os, so why
drop the support? Should it not be easy to implement ?

And why are we not sending ground troops in to fight the taliban?


Thank you,

Steve Richter

It's not really a function of TN5250.  Rather it is a function of the
emulator at the receiving end.  **IF** the emulator can connect as a
graphics-capable device (i.e., 5292) then these orders will work.  The base
Virtual Terminal support used by Telnet allows 15 different device types to
be used.  5292-2, 5555-G01, and 555-G02 are graphics capable devices (the
last two are also DBCS capable).  However most emulators don't let you
choose the device type.  They just let you choose a screen size and they'll
pick a device, usually colour, that supports that screen size.  Thus most
emulators simply support two device types (one that handles 24*80 and one
that handles 27*132).  Very few provide support for the graphics device
types.

Again, GDDM should work if the emulator provides emulation for a
graphics-capable device.
