RE: ATTENTION Key

Peter and Paul:

Thanks for your suggestions. The IP works just like the manual says. When a 
user presses it, they exit from the application they are working in. What's 
supposed to happen, and what DOES happen in 3270 emulation, is they are 
allowed to switch to another application. You might think of it as the same 
as pressing ALT-TAB in Windows; you can switch from one app to another. 
Since it doesn't work that way with TELNET we decided to chuck it and go 
with 3270 emulation.

it
is likely that IP indeed maps to SYS ATTN under TN5250 and TN3270. Do
not be alarmed about the name Interrupt Process, or the TCP manual's
claim that it "Interrupts, cancels, or suspends a process that has
started on the server system." You're sending the signal to an entirely
different layer of the communcation link, and the telnet server is
going to intercept that function and remap it before it hits the
actual process that you're running on the remote machine. We've
experimented with it, it looks like the telnet server maps IP to SYS
ATTN, so that's what you should try.

So to create the 3270 ATTN function from your AS/400 Telnet Client, you 
should press the ATTN key to get the Telnet functions menu. Choose option 1 
to send a Telnet IP request to the TN3270 server. The server should change 
the IP request into the 3270 ATTN command when it sends your Client 
response to the mainframe.
If this procedure doesn't work, check the definition of the device to which 
your AS/400 Telnet client is being connected on the TN3270 server to make 
sure that it is defined to be an SNA device.
