8051
The Intel 8051 is a Harvard architecture single chip microcontroller (µC) which was developed by Intel in 1980 for use in embedded systems. It was extremely popular in the 1980s and early 1990s, but today it has largely been superseded by a vast range of enhanced devices with 8051-compatible processor cores that are manufactured by more than 20 independent manufacturers including Atmel, Maxim IC (via its Dallas Semiconductor subsidiary), NXP (formerly Philips Semiconductor), Winbond, and Silicon Laboratories. Intel's official designation for the 8051 family of µCs is MCS 51.
Intel's original 8051 family was developed using NMOS technology, but later versions, identified by a letter "C" in their name, e.g. 80C51, used CMOS technology and were less power-hungry than their NMOS predecessors - this made them eminently more suitable for battery-powered devices.

The 8051 is used to control the keyboards of many PC's.
All math operations must use the accumulator register and the opcodes
are all pretty much the same as the more advanced 8086.
I don't know...
hello,
i have to write an assembler code for the 8051 microcontoller.
the division of two signed int numbers (range -32768 to 32767).
can someone post the code?

It can still be anything, impossible to tell. A wild guess would be that you switched rx and tx the wrong way, that's the most common RS-232 problem.
