Modern systems that lack physical serial ports usually provide
serial-over-LAN via IPMI, Intel AMT, or similar, if enabled in the
motherboard firmware.

pkgsrc has sysutils/ipmitool and sysutils/amtterm for interacting with
IPMI and Intel AMT, and on some (most?) IPMI systems you can also get
at the serial-over-LAN with ssh.

(Yes, you should do this only on wired networks you handle carefully;
the firmware implementing these things is of questionable security and
sometimes difficult to update safely, &c.)
