AutoRx
R/W
0
Auto Receive LAPD Message
This bit configures the Receive HDLC Controller Block #1 to discard
any incoming BOS or LAPD Message frame that exactly match
which is currently stored in the Receive HDLC1 buffer.
0 = Disables this “AUTO DISCARD” feature
1 = Enables this “AUTO DISCARD” feature.
3
Tx_ABORT
R/W
0
Transmit ABORT
This bit configures the Transmit HDLC Controller Block #1 to trans-
mit an ABORT sequence (string of 7 or more consecutive 1’s) to the
Remote terminal.
0 - Configures the Transmit HDLC Controller Block # 1 to function
normally (e.g., not transmit the ABORT sequence).
1 - Configures the Transmit HDLC Controller block # 1 to transmit
the ABORT Sequence.
2
Tx_IDLE
R/W
0
Transmit Idle (Flag Sequence Byte)
This bit configures the Transmit HDLC Controller Block #1 to uncon-
ditionally transmit a repeating string of Flag Sequence octets (0X7E)
in the data link channel to the Remote terminal. In normal condi-
tions, the Transmit HDLC Controller block will repeatedly transmit
the Flag Sequence octet whenever there is no MOS message to
transmit to the remote terminal equipment. However, if the user
invokes this “Transmit Idle Sequence” feature, then the Transmit
HDLC Controller block will UNCONDITIONALLY transmit a repeat-
ing stream of the Flag Sequence octet (thereby overwriting all out-
bound MOS data-link messages).
0 - Configures the Transmit HDLC Controller Block # 1 to transmit
data-link information in a “normal” manner.
1 - Configures the Transmit HDLC Controller block # 1 to transmit a
repeating string of Flag Sequence Octets (0x7E).
NOTE:
This bit is ignored if the Transmit HDLC1 controller is
operating in the BOS Mode - bit 0 (MOS/BOS) within this
register is set to 0.
