## Description

Just connect a USB serial adapter into USB OTG port of your Android device, start this app and connect to it using any Telnet client like:  
\* JuiceSSH using the same Android device (connect to the localhost)  
\* Termux and standard Linux telnet client (also, connect to the localhost)  
\* Telnet client on a computer on the same network (connect over Wi-Fi)  
  
This method allows to use all console features like colors and special keys. So you can easily control/install something like network devices with serial port using only your Android device. Also, you can use it as remote console transmitter.

\* FTDI FT232R, FT232H, FT2232H, FT4232H, FT230X, FT231X, FT234XD  
\* Prolific PL2303  
\* Silabs CP2102 and all other CP210x  
\* Qinheng CH340, CH341A  
  
Some other device specific drivers:  
\* GsmModem devices, e.g. for Unisoc based Fibocom GSM modems  
\* Chrome OS CCD (Closed Case Debugging)
