Re: [chirp_users] Problem Uploading on FT-897D
OK I couldn't leave it alone.......not solved but new interesting data........
I ran "process explorer" and "portmon" from the Microsoft sysinternalssuite. They do not show any program or process using the serial port when the error occurs (radio immediately displays "error" after A button pushed to upload when in clone mode). Appears there is not another application capturing the serial port and changing levels.
I even disabled the modem (COM3) just in case......no change....shot in the dark
I connected the USB to Serial cable to one of the Dell USB ports and it assigned COM6. I plugged the serial cable from the radio on the end and everything works great (upload and download). Looks like it is not a system software problem. I am starting to think I have a hardware problem on COM1 serial port. But it downloads fine and the HRD suite of products run fine through it. Wish I had all of the test equipment (scope, etc) I threw out when I downsized and moved after retiring. Wait a minute, I think I have a logic probe out in my toolbox......
Oh, to only go back to the days when I could simply use the system maintenance panels to displays signal levels and logic prints to track down what was happening <sigh>.
Suggestions welcome.......
Hi John

... CUT ...
Suggestions welcome.......
...mmm... interesting .... which cable are you using? Do you have the schematic? Could it be that it send spurious chars to the radio when the com port is not open? You can test trying again opening com1 with Hyperterminal before placing the radio in clone.
I'm definitively curious!!

Did I see in the messages from John somewhere that a usb port was set at 9600 baud hence a miscommunication ?

When the radio is in clone mode communication always take place at 9600 baud no matter what is sent in menu.
