>Here is a patch that makes "TTY" and "noTTY" booleans. Ah, but the former is not. :-( It's string-valued: `TTY' The TTY to use for debugging I/O. but its negator is Boolean: `noTTY' If set, goes in `NonStop' mode, and would not connect to a TTY. Wacky, eh? You'd think one should set TTY to '' to achieve noTTY. --tom
