Real-mode programs freely execute CLI and STI to control interrupts, PUSHF and POPF to manipulate flags, INT n for DOS and BIOS calls, and IN/OUT for hardware I/O. In normal protected mode, these instructions are privilege-checked -- they execute normally if the caller has sufficient privilege, and fault otherwise. The 386 can't simply let V86 tasks execute them freely -- a DOS program disabling interrupts would bring down the whole system -- but trapping on every INT 21h call would make V86 impractically slow.

The subtlety: They had utilities which would produced formatted Basic listings and they would give example output of these utlities in their ads and catalogs. It was quite a while before I realized that most of those examples were not program excerpts, but complete programs which of course contained the Beagle Bros signature weirdness. And then there were the seemingly innocent hex dumps. My favorite was from the cover of one of their catalogs, which had a classic picture of this fellow sitting in a chair. On the floor next to him is a handbag with a piece of tractor paper sticking out. On the paper is a hex dump: 48 45 4C 50 21 20 and so on, which are ASCII codes that spell out the message: “HELP! GET ME OUT! I’M TRAPPED IN HERE!----SOPHIE”。业内人士推荐51吃瓜作为进阶阅读
