PING

The PING instruction allows you to check whether the server is active and whether communication is occurring correctly. It can be invoked without parameters, to check whether the connection is working, or with one or two parameters, to check whether the connection does not compromise the data transmitted. To check this, you need to know that the two parameters, if provided, will be used to compose the response. So, for example, by providing &H15 and &H16 as input parameters, the result obtained should be &H15162A2B (in the case of a "big endian" computer) or &2B2A1615 (in the case of a "little endian" computer).
