For tcp (udp) this command is also used to check the general status of last waiting operation. Status string "error" may be given to check if connection is closed already. Check for timeout or error may be also performed just after opening of connection by command OPEN   PARAMETERS: <interface's type> <interface's name>
Opens interface of given type. Types: eth, ip, tcp, udp. For tcp this command will wait till connection with server is established or a client connection is accepted. For other types the command won't wait. See more in -d,-p,-T options.

In the case of negative value its absolute value will be obtained as timeout, but WAIT   PARAMETERS: {accept | drop | any }
Waits for packet whose mask is defined above. The command will finish work when such packet is received on waitable interface. The waitable interface is interface for which strict request (accept or drop) have been specified in parameters to command or in defaults (command DEFAULT). For TCP device the command will only wait data on the main interface. In the general case command may wait no one but several packets (added by ADD   PARAMETERS: 
Alias of TOWAIT command.

Defines the timeout for WAIT command (and its analogs), also for imitation of application's work. Null value means infinite timeout (such timeout will not be applied for imitation of application's work). In the case of negative value its absolute value will be obtained as timeout, but WAIT command (its analogs) will work differently: it will always wait for the whole timeout (not terminating on first received packet). So several packets may be registered as received. This command also defines the timeout for TCP server while waiting for connections.
