significantly simplifying the code and improving its portability. It also adds a delay option from OpenBSD to make the display go at a useful speed on fast terminals, and fixes signal handling to make it reliable. Patch supplied by Joseph Myers <jsm28@cam.ac.uk> in PR 6659.

.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl d Ar delay
|
|
.Sh DESCRIPTION
|
|
The output of
|
|
.Nm
|
|
is modeled after the
|
|
.Tn VAX/VMS
|
|
program of the same name.
|
|
To obtain the proper effect, either the terminal must be set for 9600
|
|
baud or the
|
|
.Fl d
|
|
option must be used to specify a delay, in milliseconds, between each
|
|
update. A reasonable delay is 120; the default is 0.
