#PYTHON EVENT DRIVEN PROGRAMMING PORTS SERIAL#
I'd call it very unusual (in my experience) to have a program open and close a serial port repeatedly. Maybe they did that to cover up this problem.:) Actually, I'm curious why you don't do the same. It opens it when it starts up, then keeps it open until it quits.

I didn't write the C++ program, but it looks like it never closes the serial port. I just have a couple of prints before and after the CloseHandle line. How did you prove which line it is? (I don't have an answer to the problem, just wanted to be sure of the information.) -Peter Hi! I had the SetCommTimeouts line commented out. Are you certain it is this line that is blocking, and not the preceding line which is a call to SetCommTimeouts()?

This is all on WinXP, Python 2.4.1, the latest pySerial and win32all. I see all of the settings, but have no idea what to try. I've looked at the settings in the C++ program, and in the serialwin32.py file and tried to set them the same as best I can, but no luck.ĭigging into the win32all stuff gets me lost quite quickly. Like I said, the C++ program never fails. It can also run for the better part of an hour with no problems then all of a sudden. It never seems to fail in the middle of a bunch of reads and writes, but only when/after the port is closed.
The failure mode with the large program is it opens the port successfully completes a bunch of back and forth talking, then hangs for a few seconds when the port is closed, and then can't reopen the port. The next open() attempt fails with the 'could not open port: (995, 'CreateFile', 'The I/O operation has been aborted because of either a thread exit or an application request.' hComPort) statement in the 'def close(self)' function of the serialwin32.py file of the pySerial package to hang for a few seconds, then return.

You can use a threading.Event to tell the. Interrupting a for loop while receiving data from a serial port. It also seems to be able to open, send 'blahblahblah', and close the port for the same length of time. The while loop program seems to be able to open and close the serial port all day. One is a big, scary, controller program, and the other, since that is the one I'm having trouble with, is a while() loop. There is a C++ program that has no problem talking to the equipment, but two Python programs have trouble.
#PYTHON EVENT DRIVEN PROGRAMMING PORTS DRIVER#
The driver for the 3410 chip creates a 'normal' comm port (like COM3).
#PYTHON EVENT DRIVEN PROGRAMMING PORTS PC#
The path from the PC is USB to a Phillips USB hub, then off of that a TUSB3410 USB/Serial converter. We have some equipment that communicates at 57600 baud RS232.
