[-- Attachment #1 --] The stock versions of biff(1) and comsat(8) cause the header and first few lines of an arriving mail message to be displayed. My (trivial) modifications to these programs add the "biff b" feature found in some other UNIX variants. In this mode, only a couple of BEL characters are sent to the user's terminal, signifying new mail without disturbing the display. I can't commit this feature because I don't have the privs, but my diffs are attached ... Andrew J.
