settings
A set of up to 10 Public Switched Telephone Network (PSTN) numbers that the driver will call when it next needs to be polled by the master station can be entered in the fields provided for Telephone Numbers.
Each phone number can be a maximum of 20 digits.
The digits can be any ASCII character from 0x20 t 0x7E.
The order of dialling is sequential according to the number 1...10 assigned.
The order itself can be rearranged via the Move Phone Number Up and Move Phone Number Down buttons.
If repeat dialling of a particular number is required, it can be entered into the list multiple times.
The Hayes modem driver configuration settings are described in the table below:
Table 21 Hayes Modem Driver Configuration settings
|
Setting |
Description |
|---|---|
|
Dial Command |
The dial command precedes the dial out phone number. Modem dial can be either pulse (decadic) ATDP, tone Attention Dial Tone (ATDT) or ATD. Range: ATDT, ATDP, ATD Default ATDT |
|
Dial Timeout (s) |
The next phone number is dialled if the DCD has not been asserted within this time. Range: 20 to 999 s Default: 90 s |
|
No Data Timeout (s) |
The driver will disconnect the modem if it has not received, or transmitted any data for this time. Range: 10 to 999 s Default: 30 s |
|
Attempt Delay (s) |
The delay before the next connection attempt. An attempt ends after either the DCD line is asserted, or all numbers in the phone list have been dialled. There are additional delays to the Dial Timeout.
The Attempt Delay is in addition to the above times. Range: 0 to 86400 s Default: 30 s |
|
Maximum Attempts |
The maximum number of connection attempts. There will be no more connection attempts from the ADVC once this limit is reached. The dial out capability is re-enabled when valid messages are received while the DCD line is asserted. If the attempts are set to 255, attempts will be unlimited. Range: 1 to 255 Default: 3 |
|
Radio Power Supply Cycle |
This determines the minimum frequency that the radio power supply will be cycled. The modems are normally powered via the radio power supply. For some modems, cycling their power is the only way they can be reset. This setting affects all modems that are using the radio power supply. Unless this is On, cycling of the radio power supply will not be possible. If two modems are using the Hayes driver, the power down will not begin unless both drivers are ready to power down. NOTE: The driver does not consider
all devices using the radio power supply, only devices using the Hayes
driver. Any other devices using the radio power supply but not using
this driver will be disrupted by a power cycle even if in operation.
Range: Off, 1 to 48 hours Default: Off |
