Have you profiled pySerial? http://pyserial.sourceforge.net/examples.html
I use it in my LX200 serial telescope package

Do not attempt to make your data transfer faster while using this
defective hardware design! Trust me on this. I have been doing serial
port data transfer since 300 baud was fast.
The problem with your data transfer speed is not your program optimization.

We are collecting data from many devices that have failed tests, and often
have 10 or more failed devices that we need to collect the data from. These
are scattered all over a large lab environment. I have a Raspberry Pi, and
No, I haven't.
But I'd be happy to give it a try. Chances are the serial I/O with this
package are more efficient
than the way my program is doing it now.
Thanks for that tip.
I'm also considering compiling my app to a compiled exe using PyPy, once I

I second the suggestion to try pySerial. I have used it for years to
control RS-232 equipment -- don't know why I did not think of that.
Like Terra-Term, pySerial will use device-level, rather than
file-level APIs to talk to the UART.
Of course, your success will depend a great deal on the
