So many of the newer computers do not have a serial port, only USB ports. Can I set this up if my computer does not have a serial port?

Yes, if you have a spare USB PORT you can purchase a USB to SERIAL PORT adapter.

This demo was actually done with a USB TO SERIAL PORT ADAPTER, since on my laptop I do not have a serial port.  I have heard that these adapters that use the FTDI chipset are the best...so look for one that uses this FTDI CHIP SET...like this one from AMAZON

Premium High Speed USB 2.0 to Serial RS-232 DB-9 Converter - Supports Windows 7, Vista, XP, 2000, 98, Linux and Mac / USB TO SERIAL ADAPTER (USB2-VE487) with FTDI Chipset

might be better with a USB EXTENDER CABLE like this one from AMAZON
