Muaha! My semi-annual contribution to the list (I hope I didn't
miss my last one :-):

===== perl here =====
sub readAndPrintTillMatch
{
	my ($theFileHandle,$theMatch,$theResponse) = @_;
	my $output;
	do {
		$output = <$theFileHandle>;
		print "$output";
		flush(STDOUT);
	} until ($output =~ /$theMatch/);
	print $theFileHandle "$theResponse\n";
	print "$theResponse\n";
	flush(STDOUT);
}

	&readAndPrintTillMatch(SOCKET,"Please enter your term type","01");
===== perl here =====

You pass in a file handle, pattern and response, and it will read
from the file handle (writing to STDOUT what it reads) until it
finds a match, then writes the response to the file handle, prints
the response to STDOUT and returns.  I use this for a mud robot
when creating new mud characters, passing in a socket :-).  Strip
out anything you don't need, and there you go!
