8.134. PING -- See Which Devices Are Present

When any Vortex device receives this command, it responds with a PONG status message. This is typically
used by the host program to determine the types and IDs of all linked devices. When used in this manner,
wildcard characters are usually given for the device type and ID so that all connected devices will respond.
In the following example, it is assumed that there are two EF2280's (device IDs 0 and 1), two EF2241's
(device IDs 2 and 3), two EF2211's (device IDs 4 and 5), two EF2210's (device ID's 6 and 7), and two
EF2201's (device ID's 0 and 1) linked together via EF Bus.
