- TESTCOM Serial Tester V.1.2 (DOS)
-
-
- TESTCOM can measure the performance of any
- asynchronous serial links, such as:
-
- - serial port adapters
- - modem links
- - serial ISDN adapter links
- - system performance bottelnecks
-
- This gives you a tool, to optimize serial communications
- throughput AND connect time charges or to localize sources
- of bottlenecks or communications errors. TESTCOM doesn't
- find the errors itself, it just gives you the tool you
- need to localize them or to measure the maximum speed.
-
- The only thing you need to use TESTCOM is the
- file TESTCOM.EXE, a serial link and/or a loop connector.
-
- The quickest way to do something meaningful with
- TESTCOM is the following:
- Take an isolated wire and short the transmit line TxD to RxD
- and the flow control line RTS to CTS at your PC's com port.
- On 9-pin connectors this is pin 2-3 and 7-8. On 25-pin
- connectors it is pin 2-3 and 4-5. Now run TESTCOM:
-
- TESTCOM (with no parameter, to see a short help screen)
- TESTCOM 115200 COM1 (to test COM1 at default IRQ4)
-
- This measures the maximum full duplex performance of your
- serial port in the given environement. It is
- calculated in characters received per seconds (cps).
- TESTCOM is very fast. It can run at more than 30'000 cps
- on a 486DX/50 in full duplex mode.
-
- This is only one simple application of TESTCOM, there
- are many more things you can test with TESTCOM.
-
- TESTCOM will not run on XT. It is a 80186 compiled version
- and runs on 286 CPUs or better. A 486 version is available.
- A german version is also available.
-
- The V.24 (RS232) interface is a platform independent
- international standard. This saves your investments into
- communications equipements. Serial ports will therefore
- continue to be important interfaces in the next years.
-
- If you plan to use this software, you must read the Textfile
- REGISTER.TXT and agree to the licensing conditions indicated
- in the file LICENCE.TXT.
-
- New versions of TESTCOM are available on CompuServe for retrieval
- in Lib 2 (Comm Utilities) of the PC communications forum
- (GO PCCOM). Online registration is also possible:
- GO SWREG and register items 4699 (Home) or 4700 (Business).
