Background Information For more information on RS232, there is an excellent WikiPedia article here: Older computers had an actual RS232 communication port, built onto the motherboard or on an expansion card. RS232 allowed long cable lengths because it used -12V for signalling. RS232 was commonly used to connect devices such as a: Modem for data communication Mouse to move the cursorpointer Telescope mount Over time, RS232 ports were no longer included in PCs, and a new technology called Universal Serial Bus (USB) came standard. USB is common to Windows PCs and Apple Mac computers, as well as Raspberry Pi and many Linux devices. Php Usb Serial Port Serial Adapter ToUniversal Serial Bus or USB lets you plug in any number of devices such as a: keyboard mouse thumb drive (USB memory stick) USB to RS232 serial adapter to convert from USB to RS232 Boltwood Cloud Sensor II USB to Serial Adapters To connect your old RS232-based devices like a modem, serial mouse, or telescope mount, you needed an adapter that converts the USB standard to an RS232 serial communication port, known as a USB to Serial adapter. USB Native Devices Some products are natively USB, and dont need an RS232 adapter, but do use the same underlying serial protocol. Examples include the: Starizona Microtouch Focuser controller Unihedron Sky Quality Meter Boltwood Cloud Sensor II Each manufacturer may provide a device driver and software to control their equipment. Php Usb Serial Port Drivers And SoftwareIt is a good idea to visit their web site to download the latest drivers and software, and then install them. Chip Makers and Adapter Makers There are several manufacturers of semiconductor chips used to make USB to RS232 serial adapters and USB native devices. The manufacturers often provide a basic device driver that allows Windows, Mac, and Linux computers to talk to their components. You must disable Serial Enumeration in the advanced driver settings, and turn off USB selective suspend eg do not allow Windows to turn off the device to save power. Tripplite Keyspan USA19HS Silicon Labs devices have exhibited problems for some users - You may want to update to the latest driver, and keep earlier driver versions if you run into problems. Prolific Technology suffered as there were counterfeit devices being sold. They changed their drivers so that older and counterfeit units no longer work. Many users have experienced poor reliability and compatibility problems with older Prolific PL2303 based devices, and these are often sold very inexpensively and under many brand names. Star Tech, Staples, Best Buy and many others sell inexpensive devices that have PL2303 family chips, and some users experience problems. Windows Update Issues Windows may automatically update drivers unexpectedly. This means it might accidentally install an incorrect driver version, or when it updates a device driver, default settings get turned back on, and you need to fix this. I recommend keeping a copy of the known-good working driver in your downloads directory in case you need to uninstall and reinstall. Php Usb Serial Port Windows 10 Major UpdatesWindows 10 major updates such as Creators Edition reinstall many device drivers, and this has led to problems with devices not working. Device Manager (devmgr.msc) disappeared with a recent Windows 10 update (late 2017, Creators Edition). It is no longer available from the usual Settings Gear, Settings, Devices. You can still run it with File Run devmgr.msc or WindowsKeyR devmgr.msc. You might want to make a shortcut on your desktop.
