& hook flash
The & dial modifier issues a hook flash signal
— the modem hangs up for a short period. Hook
flashes are commonly used with PABXs to transfer calls.
For example:
To dial 0, hook flash and then dial 12345:
• Type: CRN0&12345 <E>
: wait for dial tone
The : modifier causes the modem to wait for a dial tone before dialling. 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.
+ When 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).
+ UK Modems. Setting S Register 7 with a value above 58 may invalidate 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>
