After having tried everything in section Serial Port Transmission problems and the serial port communication still doesn't work, you can try to substitute the TRIA NC with a second PC in order to establish what's wrong.
There are two levels of tests that we suggest.
test n.1
- connect the PC that the customer wishes to use for serial transmission not to the TRIA but to another PC (let's call it PC2), using the same cable that is normally connected to the NC.
- Load the Columbia University kermit.exe and mskermit.ini in PC2, run it, check that the communication parameters match using the command: show comm if they do not match, change using the commands set port com1 (or com2) set speed 2400 set parity none set the Kermit in server mode: type the command: server
- Now PC2 is emulating the NC.
- Try to use the other PC and send some files.
- If this works, there is something wrong in the NC.
- If this doesn't work, you can try to use a different program: the terminal emulator that is shipped in Windows 3.1, Windows 95, Windows 98 and Windows NT. In Windows 95 and 98, the terminal Emulator program is called "HyperTerminal".
test n.2
- Using the two PCs as before, connected with the same cable, run the terminal emulator program in both the PCs. Set the communication parameters to 2400 baud, 8 bits, no parity and 1 stop bit. If you type a character in one PC, the character should be seen in the other PC and vice versa.
- This test MUST work. If not it means that there is something wrong in either the first PC, the cable or the second PC.
