The title is from:
http://www.patientecare.com/ser_port_doc/WinPorts.htmlIt is a well written article about Serial (RS-232) CCOM port assignments in Windows. Attention is given to the use of USB adapters to provide addition COM ports. Here is just part of the introduction:
Windows serial ports are numbered upwards starting from one, such as COM1, COM2, etc. Many of today's modern computers have only one RS232 serial port, or even none. If you do not have a serial port available, you must use a USB->Serial converter. These USB devices plug into an available USB port on your computer and provide one or more RS-232 serial ports for older device
It seems that many are now using such USB serial adapters, but it is hard to find clear documentation. If this is of interest too you, or if you can clarify what the above author says, please leave a comment.
