Many software packages allow symbolic naming. If you or a script created a symlink called serialzws, verify it still exists:
Linux:
file /dev/serialzws
ls -la /dev/serialzws
If it's a broken symlink, recreate it:
sudo ln -s /dev/ttyUSB0 /dev/serialzws

When seeking help, do not ask "What is serialzws?" Instead, describe the full context:
"I am using [software/hardware name]. In the log file, I see 'Waiting for serialzws.' My USB serial adapter is on COM5. How do I remap COM5 to be recognized as 'serialzws'?" Many software packages allow symbolic naming
This approach yields solutions, not definitions.
