TCPUDP Terminal is a free Android application developed by NEXT PROTOTYPES. It falls under the category of Social & Communication. This program allows users to establish TCP and UDP connections and communicate through a simple terminal interface.

In ASCII mode, the characters " @0x0D " are replaced by " \r " (CR) and " @0x0A " are replaced by " \n " (LF). This application supports both ASCII and HEX commands, providing flexibility in the way users interact with the terminal. Additionally, users can choose between being a client or a server in TCP connections.

It is important to note that TCPUDP Terminal requires certain permissions for saving log files, namely WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE.

Overall, TCPUDP Terminal is a straightforward and useful tool for establishing TCP and UDP connections and communicating through a terminal interface on Android devices.
