[Partially solved] ISR from SoftwareSerial port

Maratk1n:
Sooo, mans, I'm an idiot. The problem was not the delays, but in input text on the display (by the same port).
Is a software port is half duplex?! :o
It turns out I can not read a package because the package is constantly sent to the same port

Please make your Posts less ambiguous.

I cannot tell from the above whether you want a half-duplex serial port
OR
whether you want a regular serial port that can send and receive simultaneously.

SoftwareSerial can only do one thing at a time - listen or talk.
