The 

 command sends ICMP (Internet Control Message Protocol) Echo Requests to a target IP address

or host name (also referred to as Ping command). 

The 

 command can be used any time while a connection profile, i.e. a bearer, is active. The bearer may

have been started either with 

, or if a service is in use, with 

. If issued although no bearer is

active or no connection profile created at all, 

 returns ERROR. 

The 

 write command starts the available service type 

, i.e. the ping command. The com-

mand returns one row for every ICMP Echo Request (max. 30 lines, see parameter 

). The last Ping

response line is followed by an empty line, then another two lines appear to report a statistic calculated from the

Echo Request responses. To stop the periodic ping type any character, e.g. "AT" or "at". After calling the ping

command the AT channel is blocked until all ICMP requests are executed. 

Sending the Ping command does not restart the inactivity timeout "inactTO" of the used connection profile (see

), i.e. if the bearer was opened with 

 the "inactTO" value remains "-1" (= inactivity timeout dis-

abled), and if the bearer was opened with 

 the "inactTO" value set with 

 remains applicable.

The Ping command can only be used to prevent that a network initiated inactivity timeout closes the bearer (see
