'Serial' object has no attribute 'fd'

Question

I am trying to use python (or python3) to evaluate the TI HDC1000EVM. I can see the device in /dev as /dev/ttyACM0 it also appears in /dev/serial/by-id/usb-Texas_Instruments_MSP430-USB_Example_E89A816F1C000500-if00 -> ../../ttyACM0

However when I try to open the device using python serial I get an error that it can't open the serial port 'Serial' object has no attribute 'fd' Anyone have any ideas why??? I tried disabling the default serial port in initdev but no luck, same error.

Thanks for ANY ideas

HAH!!!! I found the cause.

Being an old timer serial programmer it has been my good practice to set RTS and DTR.

NO!!!!! I did a line by line check and the setting of either caused the no attribute fd error.

Plugging along, I am getting returns from the module in fact more than expected.

Thank you
