Report a Bad Link
Two different test methods are provided. The first test method uses two telephone lines and two modems in a master / slave configuration. The master dials the phone number of the slave modem and after a successful connection, data packets are exchanged between the master and slave. The second test method requires only a single modem and no telephone line. A local loop back is done on the analog side of the modem, ModemTest then sends data packets which are echoed back by the modem. In both cases ModemTest communicates to the modem using a COM port. (In the case of Internal modems or USB modems, this is a virtual COM port and not a physical plug on the machine).
Before sending any data ModemTest first checks the settings on the serial port and then on the modem itself. Any data received is verified to be sure that it is complete and without errors. A log of the activity is kept in the right hand section of the window. Different types of activity is highlighted in different colors. Any errors are displayed in red. This log can be saved to disk if required.
Using the file transfer options, ModemTest also assists in modem compliance testing against the International Telecommincations Union ITU v.56 ter standard. (c.f. Test procedure for evaluation of 2-wire 4-kHz voiceband duplex modems, ITU-T v.56 ter, version 08/96, sections 6.1 and 6.2).
We have discontinue support & development on our ModemTest application as of May 2012. ModemTest was originally developed and released more than 10 years ago. This was in the era when dial up modems were a popular means of getting on the internet and a solution to test the reliability of modems according ITU standards to was in demand. Times have now changed, wireless, ADSL & cable have made the dial up modem redundant, and our ModemTest software with it.
The final release of ModemTest has removed the license requirements and turn it into free software. So while the software will now be free we don't plan on providing any support for it.
