Advantech PCM-3601 user manual AT&P0DP, Getting Started

Page 10

Most popular communication software packages allow users to specify a command string and the dialing prefix that is sent to the modem prior to dialing telephone number digits. The dialing prefix reconfigures the modem according to your commands.

Below are some examples of a dialing prefix string:

ATS0=3	Instructs the modem to auto-answer an
	incoming call on the third ring.
ATX4DT9W	Instructs the modem to first tone-dial the
	number 9 and hold it until a dial tone is
	detected.
ATS6=10DP	Instructs the modem to wait for 10 seconds
	before proceeding to dial.
ATM2L3DT	Turns on the modem monitoring speaker at all
	times, and uses high volume.
ATB0DT	Uses the CCITT protocol to establish
	connection with the remote modem.
AT&P1DP	Pulse dials with the make/break ratio of 33/67
	(for use in most European countries).
AT&P0DP	Pulse dials with the make/break ratio of 39/61
	(for use in the USA).

You may use any command or combination you need. Refer to the chapters in this manual regarding modem commands for more details.

4)transmit or receive a text message or spread sheet data, or, perform whichever on-line data communication tasks you require.
