dual serial comm. to/from a micro-processor

[den372]

Hi, Has anyone had experience with dual or triple serial communication say rs232 with multiple devices to a single micro-controller (microc)? I need a microc to be able to serial comm. with a computer and a different microc. These comm do not have to occur simultaneously. My micro only has one serial in/out port Any input on this matter is appreciated

You can do serial IO entirely in software. It is know as bit-bang.

What micro controller and language are you using ?

Thanks for the reply. I am using a BASIC Stamp 2p 40-Pin Module and I am trying to interface this with a PC and another BASIC Stamp 2p 40.

Use Hardware Serial port of Basic Stamp with PC and use SPI or I²C with another Basic Stamp.I think you can use so many other devices on that same SPI or I²C.
BTW Bit banging is a still good option but I think might require good Programming wheres SPI,I²C are much simpler,faster and secure than Classical Serial Communication.
