Dial
P: Your DataPort 2001 is configured for DTR dialing (&M2
or &Q2), but does not dial. (This is used for
synchronous applications only.)
S: Verify that the telephone number stored in directory
location 1 is correct. Also verify that the computer is raising
DTR from Off to ON to initiate a dial. The state of DTR is
indicated by the TR light.
P: The message NO DIALTONE appears after dialing a
telephone number.
S: Make sure that the telephone cord is connected to the
DataPort 2001 and wall outlet. Dial the telephone number
again.
S: Attach a telephone directly to the wall outlet and verify that
a dial tone exists. If one does not, contact your local
telephone company.
S: Make sure that no additional characters are sent to the
DataPort 2001 during the connection process. The
DataPort 2001 automatically aborts the call if it receives
any.
S: Use the ATM1 or ATM2 command to turn the speaker ON
and listen for a dial tone. If no dial tone is heard, you may
have a bad telephone cord.
S: Disable the Dial Tone Detect command (X0, X1, and X3)
and dial the telephone number. This forces the DataPort
2001 to dial without detecting a dial tone on the telephone
line. This type of dialing is known as Blind Dialing.
