telnet has been deprecated all over the place because it is horribly insecure. There are mush better ways to connect to a remote machine,
starting with ssh.

nc -ct example.com 23

That too, though finding anyone who willingly has a relent port open is
very rare anymore.

Straight from nc's manpage:

'The nc (or netcat) utility is used for just about anything under the
sun involving TCP or UDP. It can open TCP connections, send UDP
packets, listen on arbitrary TCP and UDP ports, do port scanning, and
deal with both IPv4 and IPv6. Unlike telnet(1), nc scripts nicely, and separates error messages onto standard error instead of sending them to standard output, as telnet(1) does with some.'

If one has been touch typing

telnet host.slt.TLD 22
telnet host.slt.TLD 25
telnet host.slt.TLD 587
telnet host.slt.TLD 80

for several decades, even

nc host.slt.TLD 22

does not come easy, let alone

openssl s_client -connect host.slt.TLD :22

The deprecation is satisfied by blocking port 23 (at least incoming)
on the firewall.
