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.)
