5.1.4.3 MDT Mode – Serial Port settings
The MDT Mode serial port settings are independent from the Host Port Host Mode
settings. The MDT mode settings are controlled by 2 S-Registers, 131 and 132. These
register control the BAUD Rate, Data Bits, Parity and Stop Bits settings for MDT mode.
These changes do not affect the settings of S-148 or the +IPR command (i.e. the host port
baud rate).
The MDT mode BAUD Rate is controlled by S-Register 131 and supports the following
data rates:
• 4800 BAUD (ATS131=4)
• 9600 BAUD (ATS131=5)
• 19200 BAUD (ATS131=7)
• 38400 BAUD (ATS131=9)
• 57600 BAUD (ATS131=10)
• 115200 BAUD (ATS131=12)
To change the Data Bits, Parity and Stop Bit settings, you would use S-Register 132. The
follow table describes each of the available combinations:
