Abstract
A modem tester includes a signal reporting circuit which can report signals received from the modem of the computer. To test the operation of the modem in the computer, test data can be sent from the modem tester to the modem in the computer and test data can be received by the modem tester when transmitted from the modem in the computer.
Claims20
A device for testing a modem, the device comprising:
- a signal reporting circuit;
- a first communication port configured to be directly coupled to a modem in a computer, thereby forming a first communication link;
- and
- a second communication port coupled to a signal reporting circuit and configured to be coupled to the computer, thereby forming a second communication link that bypasses the modem, wherein the first and second communication links provide separate paths to the computer,
- wherein the signal reporting circuit is configured to send an initiation signal to the computer via the second communication link to initiate testing of the operation of the modem, wherein the signal reporting circuit is configured to receive first test data from the modem via the first communication link and is configured to receive second test data via the second communication link,
- and wherein the signal reporting circuit is configured to verify the first test data by comparing the first test data with the second test data.
3 more elements
A portable device for testing the operation of a modem, the device comprising:
- means for coupling to a modem in a computer via a first communication link;
- means for coupling to the computer via an alternate communication link that bypasses the modem, wherein the first and alternate communication links provide separate paths to the computer;
- means for generating and sending a signal to the computer via the alternate communication link to initiate testing of the operation of the modem in the computer;
- and
- means for verifying test data transmitted from the modem, wherein said means for verifying is configured to receive a first transmission of the test data via the first communication link and to receive a second transmission of the test data via the alternate communication link, and wherein the means for verifying is configured to compare the first transmission of the test data with the second transmission of the test data.
2 more elements
An apparatus comprising:
- one or more computer processors of a modem testing device configured, to send a signal to a computer via a first communication link to initiate testing of the operation of a modem in the computer;
- and
- one or more computer processors configured to, verify a first transmission of test data received from the modem via a second communication link by comparing the first transmission of test data with a second transmission of test data received via the first communication link.
