I don't think Wal-mart acknowledge that RS232 exists, to be honest. I
went in the other day to see how much they charged for a USB-serial
adapter and they didn't appear to stock them (but they did have
USB-parallel adapters, which suggests they know that USB adapter
gadgets do exist)
I've found them at Staples and OfficeMax, but even then they are
hard to find. Anything dealing with serial ports is getting hard
to find, including cables, genter changers, and null modems.
