3.8.1 Function of serial port & debug port supporting 

Serial port 

z

 

Seven lines on Serial Interface. 

z

 

Contains Data lines TXD and RXD, State lines RTS and CTS, Control lines DTR, DCD and 
RI. 

z

 

Serial Port can be used for CSD FAX, GPRS service and send AT command of controlling 
module. Also Serial Port can be used for multiplexing function. The module supports only 
basic mode of multiplexing so far. 

z

 

Serial Port supports the communication rates as following: 
75,150,300,600,1200,2400,4800,9600,14400,19200,28800,38400,57600,115200 Default as 
115200bps. 

z

 

Autobauding supports the communication rates as following: 
4800, 9600, 19200, 38400, 57600 and 115200bps. 

 
After setting the fixed baud rate or Autobauding, please send “AT” command at that rate, the serial 
port is available when it respond “OK”. Autobauding is not compatible with multiplex mode. 
Autobauding allows the GSM engine to automatically detect the baud rate configured in the host 
application. The serial port of the GSM engine supports autobauding for the following baud rates: 
4800, 9600, 19200, 38400, 57600, 115200bps. Factory setting is autobauding enabled. This gives 

M10_HD_V1.00
