IPRTS
The display station controls the RS-232C signal line using
(-~
~)
IPRTS (induced permanent request to send). IPRTS
handles the CTS (clear to send), RLSD (received line
signal detect), and DSR (data set ready) signals as if the
signals were always on. This parameter is effective when
RS-232C
is selected for the interface. IPRTS is equivalent
to "EIA Port, Data Leads Only" in the DEC VT220.
PRTS
The display station controls the RS-232C signal line using
PRTS (permanent request to send). PRTS handles the
CTS, RLSD, and DSR as modem signals. This parameter
•
is effective when
RS-232C
is selected for the interface.
PRTS is equivalent to "EIA Port, Modem Control" in the
DEC VT220.
Break
NORMAL
The display station sends a 500 ms break signal to the host
system when the
Break
key is pressed.
SHORT
The display station sends a 170 ms break signal to the host
system when the
Break
key is pressed.
NO
The display station does not send a break signal to the
host system when the
Break
key is pressed.

OFF
When
