Part 1 – AT Commands for All Universal IP Devices

Chapter 3 – POP3 AT Commands

#POP3UN – Set POP3 User Name

Description: User name for POP3 account. To retrieve email messages sent to a specified email address, the TCP/IP stack software must know the POP3 user name that has been set for that email account.

Syntax: AT#POP3UN="<value>"

AT#POP3UN? Read or display the current setting (or AT#VPOP3, AT#VALL).

Values: Alphanumeric ASCII text string up to 64 characters. No default.

#GETMAIL – Retrieve Host Mail

Description: This command allows the attached host to direct the TCP/IP stack to retrieve the first mail present in the POP3 server list. Once an IP link is established, the attached host can retrieve an email message at any time (except when the TCP/IP stack software is already in a process using TCP resources). This command is similar to a “check email box” feature issued by a standard messaging client on a PC.

Syntax:	AT#GETMAIL
	Command	Possible Responses
	AT#GETMAIL	Ok_Info_Mail
		<mail content>
	Note: Retrieve Notes: This message is issued when one email message is located in the
	mail	specified POP3 mailbox.
		Depending on the #POP3HEADERMODE parameter, the TCP/IP stack
		sends the email header over the serial port to the attached host.
		The (CR)(LF)(.)(CR)(LF) sequence indicates the end of the email body.
	AT#GETMAIL	Ok_Info_NoMail
		Note: There is no email to retrieve in the POP3 mailbox.
	AT#GETMAIL	#CME ERROR: 38027
		Notes: The address of the POP3 server has not been resolved by the
		secondary DNS server.
		TCP/IP stack is not able to reach the primary and secondary DNS
		servers or a wrong POP3 server address has been entered.
	AT#GETMAIL	#CME ERROR: <value>
		Notes: An error has occurred during the communication with the remote POP3
		server. It may also happen during the data transfer after the MAIL
		message. In this case, it is preceded by a (CR)(LF)(.)(CR)(LF)
		sequence.
		This error can be due to one of the following reasons:
		- The DNS servers are not able to resolve the POP3 server address
		- The POP3 server is temporarily out of service
		- The authentication (POP3UN, POP3PW) is not valid

See section ‘Response messages and error codes’.

To view parameters, use #VPOP3

#VPOP3 – POP3 Module Parameters

Syntax: AT#POP3?

Values: POP3HEADERMODE

POP3PORT

POP3PW

POP3SERV

POP3UN

POP3VERBOSE (for MT810SWM-IP only).

No default
