Multi-Tech Systems, Inc. AT Commands for Wireless Modems with IP Connectivity (S000333D) 66

Retrieving Email

This example covers the following: Retrieving email from a POP3 account.

Description: This command allows another processor (attached equipment) to instruct the modem to retrieve an

email message. While the modem is connected to the Internet, the attached equipment can retrieve an

email message at any time (except when the modem is already in the process of sending or retrieving

email, in an FTP process or socket TCP process). The 'AT#GETMAIL' command sent over the serial

port instructs the modem to retrieve one email per retrieve command.

Retrieving email

• The modem sends an 'Ok_Info_Mail' message, before sending the email over the serial port if

any are present. This message notifies the host to switch from command mode to data mode. At

the end of the data flow, the sequence [CR][LF]. [CR][LF] notifies the host to switch from data

mode to command mode.

• - When there is no mail waiting in the POP3 account, the message 'Ok_Info_NoMail' is sent by

the modem over the serial port.

AT# Command: AT#GETMAIL

Notes:

• The communication session must be established (AT#CONNECTIONSTART) before sending the

‘AT#GETMAIL’ command. After the retrieval process, the modem keeps the communication

established.

• When the email is retrieved, it is deleted from the POP3 server.
