ATH
ATH is a hang-up command. When given in the AT command mode typing ATH closes the current
connection. When given as a response to the incoming connection request (RING) ATH causes the
connection request to be rejected.
Example of closing active data connection:
+++
OK
ATH
↵
OK
ATO (Switch from AT mode back to data state)
When the data state is temporarily suspended (with command: +++) the ATO command reactivates
the data state. If the connection is still on the ESERV-10 returns “CONNECT”. Otherwise “NO
CARRIER” is returned.
Example of switching from data mode to AT mode and back:
+++
OK
ATO
↵
CONNECT
ATA
ATA is the Answer a call -command. The ESERV-10 informs an incoming data connection request
by submitting succeeding “RING” commands with intervals of two seconds. User can accept the
connection with the ATA command.
Example of allowing the incoming data connection:

AT+CMGS=
This command sends e-mail to the default or the last recipient with a subject configured in the
ESERV-10’s internal settings. After the command type the e-mail text and end with a CTRL-Z or
ESC character. If the e-mail is delivered successfully ESERV-10 returns “+CMGS: 21 OK”. For
failed E-mail transmission an “ERROR” is returned.
Example of sending e-mail:
AT+CMGS=
↵
>This is my mail <CTRL-Z>
+CMGS: 21
OK
AT+CMGS=”recipient@recipient”
Functionality of this command is similar to the plain AT+CMGS= but recipient’s e-mail address is
given as a parameter.
