Section Four
Receiving an Incoming Call
Your communications software may be able to accept incoming calls
automatically or semiautomatically. Refer to your communications
software documentation for information.
If your communications software can not automatically accept incoming
calls, start your communications software and follow these instructions to
receive a call.
You can set your Trumpcard Modem to auto-answer incoming calls using
the S0 register. The S0 register contains the number of rings before
answering and can be any number from 0 to 255 (Zero rings means do
not answer).
If the Modem is not set to auto-answer and an incoming call arrives, the
Modem will respond with a RING prompt. To answer the call, enter:
ATA [ENTER]
This tells the Modem to respond with a carrier signal. Once the connection
is established, the Modem will prompt with CONNECT.
Setting up for a Cellular Connection
The Trumpcard Modem with the cellular option supports direct connection
to cellular phones, eliminating the need for other intelligent interfaces.
In order to set up the Trumpcard Modem to recognize and control the
cellular phone you are using, software provided with the optional cellular
kit must be uploaded to the Modem. Once the software is uploaded, the
cellular operation is transparent to any communications software you may
be using.
