Ships can scan for wormholes using sensor sweep or WRS. Exact scanning rules are documented on the formulas page. Only wormhole entry points can be seen this way, the exit point of a unidirectional wormhole will not be seen!
The results of a scan are reported as messages and through util.dat. For Winplan clients, wormholes are mapped to Ufos. PHost allocates two Ufo slots for a bidirectional wormhole, one Ufo slot for a unidirectional wormhole. PHost uses up to 200 Ufo slots starting with WormholeUFOsStartAt. Existing Ufos in that range will not be seen.
Ships can travel through wormholes. If WrmVoluntaryTravel is enabled, travel is voluntary. Ships must move into the wormhole entry point and set their friendly code to WRT to say that they want to travel through the wormhole. If WrmVoluntaryTravel is disabled, ships will move through wormholes simply when they enter the wormhole entry point, no matter whether they want or not. You need not scan a wormhole before you can enter it. See Traveling through wormholes for more details.
Wormhole travel imposes stress on the wormhole. That, plus the general instability of the wormhole, put the ship on risk of being damaged by the ride.
You cannot tow or intercept through a wormhole. Unless enabled in configuration (WrmTravelCloaked), ships must decloak after the ride.
