Flag Sequence. Reports transmission status of the Flag sequence in HDLC mode, or
transmission of a constant mark in parallel asynchronous mode.
Guard Tone Enable. Enables transmission of the 1800 Hz guard tone (CCITT
configuration only).
High Level Data Link Control. Enables HDLC protocol support in parallel data mode.
Eye Fix. Forces EYEX and EYEY serial data to be rotated equalizer output.
I/O Register Select. Specifies that the X RAM ADDRESS (XADD) is an internal I/O
register address.
Loop 2 (Local Digital Loopback) Activate. Selects connection of the receiver’s digital
output Internally to the transmitter’s digital input (locally activated digital loopback).
Loop 3 (Local Analog Loopback) Activate. Selects connection of the transmitter’s
analog output Internally to the receiver’s analog input (local analog Ioopback).
Leased Line. Selects leased line data mode or handshake mode.
NEWC Interrupt Active. Reports that the cause of an interrupt request was completion of
a configuration change. (See NEWC and NCIE.)
NEWC interrupt Enable. Enables the assertion of IRQ and the setting of the NCIA bit.
New Configuration. Initiates a new configuration; cleared by the modem upon
completion of configuration change. This bit can cause IRQ to be asserted. (See NCIE
and NCIA.)
New Status. Reports the detection of a change In selected status bits. This bit can cause
IRQ to be asserted. (See NSIE and NSIA.)
change. (See NEWS and NSIE.)
(See NEWS.)
Disable V.25 Answer Sequence (Data Modes), Disable Echo Suppressor Tone (Fax
Modes). Disables the transmitting of the 2100 Hz CCI1T answer tone when a handshake
sequence Is initiated In a data mode or disables sending of the echo suppressor tone in a
fax mode.
Overrun Error. Reports overrun status of the Receiver Data Buffer (RBUFFER).
Originate. Selects originate or answer mode.
Parity Error. Reports parity error status or bad CRC
PN Success. Indicates that the receiver has detected the PN portion of the training
sequence.
Relay A Activate. Activates the RADRV output.
Parity Select. Selects stuff, space, even, or odd parity in the asynchronous parallel data
mode.
NEWS Interrupt Active. Reports that the cause of an interrupt request was a status bit
NEWS interrupt Enable. Enables the assertion of IRQ and the setting of the NSIA bit.
