**************> QUESTION level 1 --> level 2 SPECIALIST <**************
Question:
one of our customers wants to connect about 50 RISC/6000 to
a Digital-alfa system running Open VMS using TCP/IP.
Emulation must be vt100 and be able to handle FMS formatted screens.
From the RISCs running telnet they are able to access the
Digital system in vt100 mode and eveything is OK till they work
in line mode running comand line comands, but when they access
their applications the terminal hangs. The application screens
are formatted by FMS (that seems to be a standard product for
screen formatting in VMS).
Any idea if we are able to handle this emulation and if yes
how?
Thanks very much in advance, best regards, Marina.

Response:
We would suggest to increase the tty speed In addition try going into
SMIT and turning the flow control to hardware. You can also issue this
command "stty add rft < /dev/tty#"
NOTE: # is the tty number that you have assigned.

Question 2:
From your reply I think you misunderstood my question: my customer
wants to connect a RISC/6000 to a DEC system running VMS using TCP/IP
over LAN. The DEC system supports vt100 terminals, so they negotiate
the usage of vt100 emulation. Unfortunately the default IBM terminfo
contents for vt100 does not allow the display of application screens
created by FMS (Open VMS standard). My question was if it's possible
and if yes, how to modify the terminfo to support FMS.
My customer says that with HP running UX they do NOT have this problem.
I suppose they modified their terminfo.
Thank you very much in adavance, best regards, Marina.

Response:
FMS is a full screen VAX Forms Management System.
This is a DEC application and I have know knowledge if they
use terminfo or anything else for control. (is is written
in curses, if not, then the issue is not really with terminfo.
You did not say what level of AIX you are using. At AIX 4,
the dec.ti file supplied with the operating system is authored
by DEC. There have been significant changes to curses in
going from AIX 3 to AIX 4 and the terminfo files change.
Is the customer using vt100 terminals, or some other terminal with
vt100 emulation?
This is a new question to the support group. No one has reported
this problem in over 4 years so we don't have all the knowledge
that might be usefull. If the application isn't curses based,
then changing terminfo won't help much. Other mapping schemes
are "setmaps" which is really character translation on input
and output.
Here are some suggestions to try:
1. Get the terminfo file from the HP system and copy it to:
/usr/share/lib/terminfo/v/vt100
and see if that works. You can always regenerate the old
one with "cd /usr/share/lib/terminfo; tic dec.ti".
2. Capture the output by running "script" before telnet'ing
to the VAX system. The output will all go to a file called
"typescript", and it will contain all the characters that
are being sent. You can examine the file with "od -cx typescript"
and compare this to the terminfo definitions. To see the
current terminfo defintions for comparison try:
"tput blink | od -cx"
"tput bold | od -cx"
"tput box1 | od -cx"
"tput font1 | od -cx"
"tput sgr0 | od -cx"
etc.
3. Does any of the screen get painted? Can we pinpoint where
this is happening?
4. I would highly recommend AIX 4 be used.
5. What changes were made to the HP system?
6. What does DEC support say about UNIX systems and telnet'ing?
Please contact your local AIX support center for additional assistance
if problems persist.
Thank you for using AIX Support services.
