1. Decide which modem is to be the Originate modem and

which the Answer modem. The originate and answer

frequencies must be defined for the modems to com-

municate.

2. First put the calling modem in Originate Mode with the

manual Dial command:

ATD

<er>

NOTE:

Be sure the modem is not set to X2, X4, X6, or

X7, or it will return the NO DIAL TONE result code and

hang up.

3. Then put the answering modem in Answer Mode with the

manual Answer command:

ATA

<er>

NOTE:

If there is an interruption in the communications link

(a strike to the line due to weather or some other problem),

repeat steps 2 and 3 to reestablish the link.
