2.1 Auto-Answer Feature
This feature enables the ConnexModem unit to answer an incoming call over the phone line. In
order to enable this feature, the HyperTerminal program must be opened. HyperTerminal is
launched by clicking on the Start icon in Windows and selecting Programs. From the Programs
list select Accessories, Communications, then HyperTerminal. Once in HyperTerminal, you must
type a name for the connection and click OK. Next to the Connect Using field, select the proper
COM Port. Make sure the Baud Rate setting is equal to the ConnexLink’s Baud Rate setting,
Data Bits equals 8, Parity equals None, Stop Bits Equals 1, and Flow Control equals Hardware.
Apply the settings and HyperTerminal is ready to send commands.
ConnexModem configuration: Broadcast, Modem Control and RTS should be enabled.
ConnexLink should be configured with default values and Auto Destination enabled.
Make sure Auto-Answer is enabled on the ConnexModem: (Refer to RC56D ATCRM.PDF for the
AT Commands)
1) Enable Auto-Answer on the ConnexModem
a. Connect the ConnexLink to a computer and start HyperTerminal.
b. Type the characters ATS0 = n command, where n = the number of rings to Auto-
Answer.
This command sets the S0 parameter to a value other than zero to enable Auto-Answer.
S0 sets the number of rings required before the modem automatically answers a call.
Setting this parameter to zero disables auto-answer mode.
2) Enable DTR On
a. Send the AT&D0 command
3) Save the Auto-Answer configuration to a modem Profile, 0 or 1.
a. Send the AT&Wn command, where n = Profile number.
4) Depending on the application, the OEM can send the AT&Yn to command or ATZn
command (where n = Profile number) to recall the Profile settings.
ATZn performs a Soft Reset and Restores Profile n. AT&Yn Designates a Default Reset
Profile, which will be used after a hard reset.
The modem is now ready to answer a phone call automatically.
Connect to the ConnexModem using a computer or another telecom Host. Once connected,
multiple ConnexLink units can communicate with the ConnexModem.
