 # Changelog
 
+## 2024.06.16
+
+ * Uart parameters can be configured with "zinc-setup" configuration utility
+
+ * EDOS now handles CTRL-C via console status call
+
+ * LU310 was fixed
+
+ * Disable VDP commands via keypresses for more correct terminal emulation
+
+ * All terminal code moved out of BIOS
+
+ * UART1 is accessible via IOByte
+
 ## 2024.06.09
 
  * Better ADM-3a terminal emulation

 You shouldn't specify file extension for executable file(`.com` will be added automatically) and directory should no contain files with long file names.
 
+### Using UART1 from CP/M Applications
+
+UART1 is accessible via IOBYTE(you can switch character input/output from terminal emulator to UART1 just changing one byte in RAM). 
+
+Before using UART use `zinc-setup` utility - it's interactive tool for setting UART parameters. 
+
 ## Terminal emulation layer
 
 Currently, it supports "ADM-3a"-like compatible terminal emulation routines(like KayPro or some other computers).
