Milltronics Cent 1 controller. I've set all the parameters on the controller and the Dell XP laptop ..... baud=1200 baud, databits=7, parity=even, stopbits=2 .... got a null modem DB9 to DB25.
Can't seem to transfer files, either sending or receiving. The Cent 1 keeps saying something about a parity bit conflict even though the parity is set correctly according to the manual.
Using the Hyperterminal on the laptop, I can sometimes see data on the laptop when I send from the Cent 1 to the laptop when I do the following .... In the hyperterminal window I select Transfer. It then asks for the name of the folder to place the data into. If I DON'T do this and hit the start button on the Cent 1, I will see the correct data going by on the laptop, but only a line at a time, so that when it's done I only see the last line. If I DO enter a receiving folder name then I get a parity error message from the Cent 1 and no data transfer at all. It would appear that the data is getting to the laptop but the laptop is unable to capture it. The file in question works properly on the mill.
I have tried various baud rates and receiving protocols (something the hyperterminal asks for, don't know which protocol is best). I have tried selecting Xon/Xoff, hardware, and "none" for the handshake. What's left to try? Totally baffled. Hopefully it's not some broken hardware.
