Test your dial up modem and telephone line for errors and connection speed
ModemTest performs low level testing of dial up modems and telephone lines. Testing is preferably done with two modems but a single modem can also be used. Tests are independent of ISP and TCP/IP settings. ModemTest logs any data corruption and incorporates a modem speed test which reports the initial connection speed and the actual throughput. ModemTest helps to isolate faults with your ISP, dial up modem and telephone line.
