* The terms in the "Name" column are the standard POSIX signal names for the subset of signals recognized by A-Shell. Note the standard signal names are associated with integer values that may vary between UNIX flavors; the bit values used by A-Shell are independent of the underlying operating system signal values, and uniform across all platforms.
