DIGital:CONTrol

:POLarity

[SOURce:]DIGital:CONTrol

:POLarity <

polarity

sets the CTL line voltage level

for logical true in port n to either TTL high for

POSitive

polarity or TTL low for

NEGative

polarity.

Parameters

Comments

•

Control lines are always accessed by their 8-bit port number.

•

:CONTrol

n is the keyword used for commands relating to the control (CTL)

line at port n. The port number n must be the last character of the keyword
without spaces.

•

If n is omitted, port 0 is used.

•

The control line is used with the flag line to handshake data to and from

peripherals.
