What these flags mean:

-a (or -alarm): Make an audible beep each time the ping test fails.
-tcp: Specifies that the TCP/IP protocol is to be used. This is assumed if -http is not specified.
-http: Specifies that the HTTP protocol is to be used. Use this when testing the availability of a website or web-server.
-smtp: Specifies that the SMTP protocol is to be used. Use this when testing the availability of an email server for receiving (or sending) emails.
-pop3: Specifies that the POP3 protocol is to be used. Use this when testing the availability of an email server for downloading (POP3) emails.
-nntp: Specifies that the NNTP protocol is to be used. Use this when testing the availability of a USENET/Newsgroup server.
-b (or -beep): Make an audible beep each time the ping test succeeds.
-d: Include a date and time stamp with each output message. The date and time are shown in YY-MM-DD HH:MM:SS format.
-p port (or -port port): Instructs CryPing to ping a specific TCP/IP port. CryPing will then try to open that port and return the time to connect and successfully open the port.
-t: Run forever until told to stop. It can be stopped by typing control-C.
-n: Ping the server the specified number of times. By default CryPing will ping the server 4 times before stopping. If you want to ping forever (or until interrupted by control-C) then use -t.
-l: Send buffer size. This is the size of the ping packet sent to the server. This is ignored when pinging a port or http.
-i: Time to live. This is the maximum number of network hops between the current pc and the remote device being pinged before the ping will fail. Ignored when pinging a port of http.
-o: Type of service.
-v (or -verbose): Verbose output. Displays header information when combined with -http. Ignored otherwise.
