Set these bits to 0 when setting Bufctrl.HDLC to 1.
HDLC (Set HDLC Mode: all data modes)
Set HDLC mode. When parallel data transfer mode is
selected (TPDM is 1) and HDLC is set, the data pump
transfers data using the synchronous HDLC mode. In
serial mode (TPDM is 0), this bit has no effect.
The host should set bits 8
–
15 to 0 when it sets this bit to 1.
SCRDIS (Scrambler Disable: V.22, V.22bis, Bell 212A)
Set this bit to disable the transmitter scrambler. This
action takes precedence over TRNCTRL/TXCTRL.
TXMHLD (Hold Tx Output to Marks: all modes)
Set this bit to force the data pump to transmit only marks
to the remote modem, disregarding data received from
the host.
DSCRDIS (Descrambler Disable: V.22, V.22bis, Bell 212A).
Set this bit to disable the receiver descrambler.
RXMHLD (Hold Rx Output to Marks: all modes)
Set RXMHLD to 1 to cause the data pump to transmit only
marks to the host, disregarding data received from the
remote modem.
