I need to prototype an Android application which communicates to external hardware using serial I/O. Can the emulator send and receive serial data over a PC's com port?
The default value is 5554 for the first virtual device instance running on the your machine. A virtual device normally occupies a pair of adjacent ports: a console port and an adb port. The console of the first virtual device running on a particular machine uses console port 5554 and adb port 5555.
This is a driver library for communication with Arduinos and other USB serial hardware on Android, using the Android USB Host Mode (OTG) available since Android 3.1 and working reliably since Android 4.2.
COM Port Data Emulator is a software application that enables users to emulate an entity, such as an Ethernet device or COM port, that transmits data as a serial stream. The program takes the data stream and converts it to data packets using serial protocols like RS232, TCP/IP or UDP.
Virtual Serial Port Emulator allows you to create an unlimited number of virtual COM ports. The software emulates serial port functionality connected by virtual null modem cable in such a way that the system does not see the difference between virtual and real hardware ports.
The Android emulator itself supports this feature, I see people use "emulator -qemu -serial COM1" on Windows PC
or
"emulatro -qemu -serial /dev/ttyS0" on Linux PC
I have not tried it by myself yet, but that is the way in the big picture.
