! (Repeat Previous Function)

The ! function repeats the most recent function executed. The following
example issues an ibsic command, then repeats that same command as
follows.
gpib0: ibsic
[0130] (cmpl cic atn)
gpib0: !
[0130] (cmpl cic atn)

- (Turn OFF Display) and + (Turn ON Display)

The - function causes the bytes received not to be displayed on the screen. This
function is useful when you want to repeat any I/O function quickly without
waiting for screen output to be displayed.
The + function causes the display to be restored.
The following example shows how the - and + functions are used. Twenty-four
consecutive letters of the alphabet are read from a device using three ibrd
calls.
