Splitting serial output microcontroller

Got a question about the serial output of a microcontroller .

I want to make a serial output signal, so that i can send a couple of pulses serial. The puls patron must be variable.

after making one serial output signal, i want to make a sort of a splitter between 6 channels. so that i can lead the signal through one of the several channels.

so the purpose is to create 6 serial output signals out of 1 serial output of the microcontroller. I was thinking about SPI or UASART.

It's for demonstrating some different output signals to a scope. Why i don't use 1 channel and change the serial software registers ? because to each output a different distortions will be added.

Some suggestions for solving this problem?

You must be a hardware guy.

Use software to simulate as many serial outputs as you like. Most C compilers include them in their library. Many examples of them on the net. Also know as "bit bang" or "bit banging" or "software uart".

Yes i am!

So i can simply made 6 serial output signals out of one microcontroller.

because there is only one or two usart or spi modules on the microcontroller, i have to do it with a shift register (created in software)?

Something like this: https://en.wikipedia.org/wiki/Bit-banging ??

Thanks for helping me out
