Developped with qemu, this is how i tested.

To start qemu

xtensa-softmmu/qemu-system-xtensa -d guest_errors,unimp   -cpu esp32 -M esp32 -m 4M -net nic,model=vlan0 -net user,id=simnet,ipver4=on,net=192.168.1.0/24,host=192.168.1.40,hostfwd=tcp::10023-192.168.1.3:23  -net dump,file=/tmp/vm0.pcap  -s  > io.txt



xtensa-softmmu/qemu-system-xtensa -d guest_errors,unimp  -cpu esp32 -M esp32 -m 4M -smp 2  -net nic,model=vlan0 -net user,id=simnet,ipver4=on,net=192.168.1.0/24,host=192.168.1.40,hostfwd=tcp::10023-192.168.1.3:23  -net dump,file=/tmp/vm0.pcap    -s  -S > io.txt

nc 127.0.0.1 10023

To test echo

xtensa-softmmu/qemu-system-xtensa  -d guest_errors   -cpu esp32 -M esp32 -m 4M -net nic,model=vlan0 -net user,id=simnet,ipver4=on,net=192.168.1.0/24,host=192.168.1.40,hostfwd=tcp::10007-192.168.1.3:7  -net dump,file=/tmp/vm0.pcap   -s  > io.txt
