When entering the next command after an escape sequence, always wait to receive
"\r\nOK\r\n". An escape attempt in the interval may fail because the modem is not
in on-line data state. There are equal guard time periods before (leading) and after
(trailing) the "+++"Timing for this escape sequence as illustrated below.
If the escape sequence is not followed by another command within 50 milliseconds
(trailing guard time), the cradle will hang up after another 10 seconds. Normally, the
terminal will receive "\r\nOK\r\n" during the 10-second interval unless the line is
abnormally busy.
Note: The Guard Time is 50 milliseconds and cannot be changed.
AT Commands Tasks
ATDT The Ethernet Cradle will create a connection with a remote PC:
By IP address – e.g. 192.168.6.123, via port 5000:
ATDT192.168.6.123:5000
By host name – e.g. www.cipherlab.com.tw, via port 1024. The IP address
associated with the host name will be obtained from the DNS server:
ATDT www.cipherlab.com.tw:1024
AT+MACID? The Ethernet Cradle will respond with its MAC ID to the terminal.
AT+GCI? The Ethernet Cradle will respond with its country code, which is fixed to FE
(=Taiwan), to the terminal.
ATXX... The Ethernet Cradle will simply respond with "\r\nOK\r\n" to the terminal.
AT+DHCP? The Ethernet Cradle will respond with "\r\nENABLE\r\n" to the terminal when
DHCP is enabled; otherwise, it will respond with "\r\nDISABLE\r\n".
ATA The terminal accepts the connection request when it receives "\r\nRING\r\n".
AT+IP? The Ethernet Cradle will respond with its IP address to the terminal.
AT+DNS= The Ethernet Cradle will be assigned with the IP address of DNS server.
AT+DNS? The Ethernet Cradle will respond with the IP address of DNS server.
AT+GWY= The Ethernet Cradle will be assigned with the IP address of Gateway.
AT+GWY? The Ethernet Cradle will respond with the IP address of Gateway.
ATS7= The Ethernet Cradle will wait for the specified period of time (5~50 sec.) for
receiving a carrier from the remote modem before hanging up.
By default, it is set to 10 seconds.
S7 – wait for carrier after dialing (ATDT...)
ATS7? The Ethernet Cradle will respond with the current setting of waiting time for
receiving a carrier from the remote modem before hanging up.
AT+IDLETI The Ethernet Cradle will wait for the specified period of time (10~180 sec.) for
MEOUT= sending/receiving data before hanging up.
