Wake-on-ring
Wake-on-Ring (WOR) or Wake-on-Modem (WOM) is a specification that allows supported computers and devices to "wake up" or turn on from a sleeping,
ACPI
state G1 or G2), and begin operation.
The basic premise is that a special
dial-up modem, telling it to fully power-on and begin operation. Common uses were archive databases and BBSes
, although hobbyist use was significant.
Fax machines use a similar system, in which they are mostly idle until receiving an incoming fax signal, which spurs operation.
This style of
remote operation has mostly been supplanted by Wake-on-LAN
, which is newer but works in much the same way.
