I just use os_printf() but in terminal I gets garbage only. Trying with baudspeed 9600 115200 74820 - nothing. Samples from SDK(blinky from
https://github.com/esp8266/source-code-examples) also prints garbage. SDK 1.0.1. PL2303 rx and tx connected to TXD and RXD pins of ESP-07 What I'm doing wrong?

Do you have this problem with just the blinky sample code? Have you tried the stock AT firmware or NodeMCU? One thing you can try to rest the module by pulling the RST pin low briefly while you have everything connected.

Post the os_printf command from your code.
Are you enclosing the text with " ?
os_printf("text");
os_printf("This is a number I want to print: %d", numbervariable);
