Disable onboard serial port

ThinOS enables you to disable the onboard serial port on the following platforms:

  • Wyse 5070 Thin Client with Celeron processor
  • Wyse 5070 Thin Client with Pentium processor
  • Wyse 5070 Extended Thin Client with Pentium processor

To disable or enable the onboard serial port, use the INI parameter Device=SerialDisable={yes, no}. The default value is no. This option does not affect the USB serial devices. The value that you specify is saved into NVRAM and a system reboot is required for changes to take effect.

After the onboard port is disabled, all the port values—COM1, COM2, COM3, and COM4—are available for USB serial device mapping. You can view the ThinOS event log to know the local serial port name that is used when a USB serial device is attached to the thin client.
