A couple of things are not very clear for me :
Novatel has plenty of device and software, which one are you using ?
Anyway, you get data, so your connection works. However, their doc mention to use 115200 bauds ; did you try ?
I understand you have a device connected to a PC. Why using a COM splitter ? If the data is coming from outside (Novatel) to the PC (windows COMn), you should just manage one port.
When you talk about 0.4 second, I assume this is 16426,023556 minus 16425,983525 equals 0,040031000000454 , correct ?
So where does the gap come from ?
1 - The device misses some data, and it does not send it ; nothing you can do at the PC level, it must be corrected on the device.
2 - The device gets and sends all the data, and the PC misses it. I saw that sometimes, but in that case the communication doesn't get correctly synchronized after a while and the data becomes suddenly unreadable, looking like blocks of strange characters. Not your case, and certainly very rare with modern computers.
3 - The virtual port software does not run well. Looks strange but not impossible. You can replace it by a null modem cable, but I don't know if it's that easy to find nowadays.
If all of that gives nothing, it's time to ask the technical support team of Novatel, and anyway, I'm pretty sure it's not a problem with python.
Best wishes of success...
