: Wait for Dial Tone V.25bis
The : modifier causes the modem to wait for a dial tone before dialing.
If the modem does not detect a dial tone within 30 seconds, it returns a
message of CFI AB, hangs up and returns to local command state.
You can change the dial tone waiting period from the default period of
30 seconds by changing the value in Register 7.
FWhen using the : modifier, the length of time your modem waits for
a dial tone is determined by the value contained in S Register 7 (Wait
for Carrier) and not the value in S Register 6 (Wait for Dial Tone).
FUK Modems. Setting S Register 7 with a value above 58 may invali-
date the approval of your modem. S Register 7 must be set to 20 before
issuing the : dial modifier.
For example:
To wait for a dial tone and then dial 111-0123:
• Type: CRN:1110123 <E>
