For PSTN connected devices - the number of times the I/O Server will try to dial a dial-up I/O device before declaring that it is OFFLINE.
For non-PSTN connected devices - the number of times the I/O Server will try to bring a device online before declaring that it is OFFLINE.
Note: If the modem is busy, the attempt will not succeed. If more than one modem is configured on the I/O Server computer, a different one will be selected for the next attempt. If there is only one modem, the I/O Server will try it again. This process will continue until an available modem is found or until the number of retries has been reached.
