hi :)

recently i've been learning about using perl to send email.
i try to look at some examples that i found from the internet.
in some example, i observed there is something like scripts below: 
if ( my $server = <$sock>) 
{
    print "Got Handshake: $server";
    dialog( $sock,  "HELO $forged_from\015\012" );
    dialog( $sock,  "MAIL FROM: $from\015\012" );
    dialog( $sock,  "RCPT TO: $to\015\012" );
    dialog( $sock,  "DATA\015\012" );
    dialog( $sock,  "$msg\015\012.\015\012" );
    dialog( $sock,  "QUIT\015\012" );
}

[download]

so, i would like to ask, what is the meaning of "\015\012" ?
is it same with "\r\n"? i see some of the example using \r\n

by the way, what is the meaning of \r? i know that \n means go to next line.

thank you very much :)
