Android Emulator Serial COM1 port crashes on data incoming from windows

[Lior3790]

Hi,
I have the following set:
* Windows 10 pro
* Android Studio Emulator 27.3.10
* Virtual Windows COM port bridge COM1 <--> COM2

I start the emulator with a clean API 25
target Android 7.1.1 for x86
with the following windows command:

emulator @Device_API_25  -qemu -serial COM1

when running:

adb shell "dmesg|grep tty"

i can see that the serial port was forwarded:

[ 0.000000] console [ttyS0] enabled
[ 2.399629] 00:04: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 2.430745] 00:05: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A

afterwards i run the adb commands:

adb root
adb shell "setenforce 0"

Now,
when sending from android shell:

echo test >/dev/ttyS1

I can see the outcome in windows COM2 port

but, when trying to send from windows:

echo test > COM2

the emulator crashes with the following information:

emulator: ERROR: detected a hanging thread 'QEMU2 main loop'. No response for 15058 ms

and the emulator crash data is (partially):

Operating system: Windows NT
10.0.17134
CPU: amd64
family 6 model 61 stepping 4
4 CPUs

Crash reason: EXCEPTION_ACCESS_VIOLATION_WRITE
Crash address: 0x0
Assertion: Unknown assertion type 0x00000000
Process uptime: not available

did anyone encountered such an issue ?
