Here are several different ways to test a TCP port without telnet.

BASH (man page)

$ cat < /dev/tcp/127.0.0.1/22
SSH-2.0-OpenSSH_5.3
^C

$ cat &lt; /dev/tcp/127.0.0.1/23

# Derived from this: https://github.com/gashton/bambustudio_tools/blob/master/bambudiscovery.sh
# Python implementation without need for linux
# Send the IP address of your BambuLab printer to port 2021/udp, which BambuStudio is listens on.

# Ensure your PC has firewall pot 2021/udp open. This is required as the proper response would usually go to the ephemeral source port that the M-SEARCH ssdp:discover message.
# But we are are blindly sending a response directly to the BambuStudio listening service port (2021/udp).

# Temporary solution to BambuStudio not allowing you to manually specify the Printer IP.
