I want to use GDB to debug a KGDB device on a remote device. However, typically KGDB operates through a serial connection (target remote /dev/ttyUSB0). To debug the KGDB on the remote device, I wrote a simple Python script that converts the serial connection to TCP. This means that using a program like Telnet, I confirmed that it is possible to connect to the remote device exactly the same as with the serial connection (see the program below).
