I'm using an old Win XP laptop, and the IDE gives me only one choice - COM3, which it won't accept. Any ideas?

Windows XP wasn't as good as nowadays when working with USB devices.
In general you first have to install the correct driver before inserting the USB device.
Since I don't have a working XP machine at hand at the moment (for obvious reasons), I'm doing this from memory:

Since I don't have a working XP machine at hand at the moment (for obvious reasons), I'm doing this from memory:
- Remove (all) USB devices that create and use COM-ports
- Download and install the latest version of driver for the used UART-USB bridge for Windows XP:
- Now plug in the NodeMCU: you should hear the low-high confirmation tone and if the device wasn't correctly registered yet, it will be now (you'll see a popup hint window)
- Go to the device manager either by navigating through the configuration panel or by opening a command prompt and entering "devmgmt.msc" without the quotes.
- Scroll down, in the tree, to the "Ports *COM & LPT)"-node: the actual COM-port of the NodeMCU should be listed here
(Screenshot of device manager in Windows 7, but it's exactly the same in XP) - This port should also be listed and selectable in the Arduino IDE

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
