Serial port conflict has not been seen for many years. A long time ago, it should be due to the disunity of hardware manufacturers, imperfect drivers and unintelligent systems.

There are many hardware conflicts, which is the origin of so-called assembly machine compatibility. There are few serial port devices now.

There are also few opportunities for conflict. Do you need a serial encryption dog to install professional software?

Encryption dogs sometimes do have such and such problems. If the redo system closes the software, turn off the power and try several times.

I hope this is strange.
