[Expectperl-discuss] Interace escape sequence

[Bryan T S. <bs...@ad...>]

I've been banging my head off the wall trying to figure out why interact 
doesn't recognize the escape sequence on Linux.  Thus far, the only 
results are holes in both my head and the wall, so I'd appreciate any 
insight into the issue.

Thanks in advance.

Source script:
#!/usr/bin/perl

use Expect;

my $exp = Expect->spawn("/usr/bin/bc");

print "Version = ", Expect::version(), "\n";

$Expect::Debug = 1;
$exp->debug(3);
$exp->interact(\*STDIN, "\027");

print "Interact exited\n";

Output from script:
