SART Messages are defined for each of the three modes (HDLC, ASYNC and Binary).
SART Configuration
•
Configuration setup
Host ⇒ ISAR
The host configures the mode (Binary, HDLC,
ASYNC) for the SART and sets further parameters
depending on the mode.
SART Data
•
Status events
with receive data
Host ⇐ ISAR
During data reception the ISAR indicates to the
host, when error conditions or mode specific
events occur, e.g. when the end of an HDLC
frame was detected.
•
Control commands
with transmit data
Host ⇒ ISAR
During data transmission the host controls
mode specific functions e.g. the HDLC framing
(frame start, frame end) and the generation of
break signals in ASYNC mode.
Pump messages are defined for all of the seven pump modes (fax modulations, datamodem modulations, halfduplex
modulations, V.110, DTMF, DTMF transmission and bypass).
Pump Configuration
•
Configuration setup
Host ⇒ ISAR
The host configures the mode (fax modulations,
datamodem modulations, halfduplex modulations,
V.110, DTMF, DTMF transmission or bypass) for the
data pump and sets further parameters depending on
the mode.
•
Control commands
Host ⇒ ISAR
The host sends control commands to the ISAR
in order to enable/disable the pump and to set
mode specific control commands (e.g. DTMF
tones to be generated).
