ISDN Data and Telephony Protocol Engine (inc. X.25)
CMX228
Incoming calls are indicated by a 'RING' result code. The call is automatically answered if S0 = 1 or
more. If S0 = 0 an ATA command must be entered, then a CONNECT message is sent to the
network.

This command tells the CMX228 whether or not to echo the characters received from the DTE when
in command mode. When echo is on, all non control characters received from the DTE are echoed
back to it.
H (Hang-up)
Format:ATH<CR>
Causes the CMX228 to clear the data call in progress. The command is not valid if there is no data
call in progress but always returns an ‘OK’ result code. It is only valid in the command state when a
data call is in operation, when it will send a DISCONNECT message to the network. Upon receipt of
RELEASE, a RELEASE COMPLETE is transmitted to the network and ‘OK’ returned to the DTE.
