Re: How do i interact with a ibm 3270 mainframe?

The first thing I'd check is if you can telnet to the IBM mainframe. Unless it's 20+ years ancient that should be possible (although possibly not enabled). If you can, Net::Telnet, Expect, or similar should do the trick.

If telnet is not an option, there are several tn3270-type programs out there that can be automated with Perl. See scraping screens from a tn3270 terminal and Re: Interact with mainframe screen for ideas.

Thx a lot for the support, i can telnet to the IBM mainframe; i went through links and ended up with the following code: `use IO::Socket; my $sock = IO::Socket::INET->new( Proto => 'TCP', PeerAddr => '161.196.25.2', PeerPort => '23', ) or die "Unable to create socket: $!\n"; #while ( <$sock> ) { print } @line=<$sock>; print @line;` [download] Unfortunately, as i run this pl, the machine just "hang up", till CTRL+C is pressed. Any examples using Net::elnet, Expect ? . Regards.	[reply] [d/l]

Yeah, no sense in using raw sockets when Net::Telnet has already been written and thoroughly tested. I don't have any examples easily available - I'd have to strip out irrelevant and proprietary code - but the EXAMPLES section of the docs is a good starting point.	[reply]
