[Expectperl-discuss] Need help with capturing output

[Hoang N. <hoa...@pl...>]

Hello -

I just started using Perl 5 and Expect-1.12 and have a problem with
obtaining 
output from a spawned process. Much appreciate if you could point out
a few things for me.

Here is the basic steps of the program:

- Spawn a telnet session into a term server (DigiBoard 8 ports) and obtain
   a object handle from that. 
   
   At this point, what happens to my STDIN, STDOUT? How can i print 
   to the screen that i started the script. 
   

- Goes through the normal login procedure with user name and such
- Enter a forever loop. In this loop
   get input from keyboard. $command=<stdin>
   If the command is one that the script understands - process it
   else send the command to the UUT (unit under test), capture the out
   put from the command and wait for prompt.

   At this point, i encountered a few problems with capturing the output
   of the UUT. Not all the output of the UUT is captured regardless of
variations
   that i tried. Is it possible that the output of UUT is buffered
somewhere? in
   Expect? in Xterm? I don't have this problem if i go into interactive mode

   ($object->interact()).

If you have done somthing like this before please drop me a line.

Thanks in advance,
Hoang
