Please excuse this question if it seems too simple but I'm sort of at my
wits end here!
We have a problem with incomming calls to PSI over DATAPAC and the interface
to VAX NOTES. What we have is a large number of users logging in from all
over Canada and the USA with the University picking up the DATAPAC charges,
therefore we are very concerned about keeping costs down. ie) no extra packets,
etc. The theory went something like this. We would have the local dial-up
X.25 node do the editing by setting the ITI parameters with the following
command:
set terminal/x29/par=(2=1,3=126,15=1,16=8)
2=1 :Makes the local DATAPAC node do the echoing.
3=126 :Forward on control signals or <CR>
15=1 :Enable local editing on the DATAPAC node.
16=8 :Set the backspace key as the del-prev-char to get the terminal
:correspond with the packet.
* We also specifically turn off the hold_timer since this is the REAL money
muncher. (par 4=0)
Since we would not allow full screen editing to take place over DATAPAC
we would force all to be unknown terminal types. We would then
set term/noecho/nolocal_echo to prevent the packet being echoed back and
therefore costing more and really making a mess of the poor user's screen.
This works fine from the system level. ie) it works like described above.
The problem comes in when NOTES is called. It seems that NOTES sets the
terminal to either echo or local_echo and when that happens the PSI X29
parameters also change. ie) parameter 2 goes to 0 and 15 to 0.
If the terminal is set to local_echo then the ITI X.29 parameters are fine,but
the packet is echoed back. When the terminal is set to echo then par 2 and
15 are changed, making it very hard to see what you are typing since the
characters are not echoed until the VAX sees them. (ie. only on a <CR> or
control sequence)
What I would like to know is this. Is it possible to
1) have a datapac user login and set the ITI parameters (Can do)
2) Lock those same parameters so NOTES can't change them.
Has anyone had any experience with this sort of thing?
