/*
 * This hack-utility opens a serial port at the user-specified baud rate
 * and drops into a terminal pass-thru mode, except that any binary bytes
 * received on this port are turned into cat -v form.  The intent is for
 * sniffing on and/or talking to targets that emit some ASCII mixed in
 * with binary.
