Here is a page documenting the RecvFrom_() function call, if you want to do direct receiving of data from a socket and also get the UDP sender's IP and Port number (I haven't checked yet if the parameters match up with those in Blitz but I presume they do):

The only part I'm not sure about is the last parameter which is referred to as a `length` and does not mention anything about a port number??
There is some mention of the Select_() function here:
http://support.sas.com/documentation/onlinedoc/sasc/doc750/html/lr2/select.htm
http://www.codersource.net/winsock_tutorial_server_select_model.html
which seems to have something to do with testing if data is available for reading, like ReadAvail()
And here is some info about ioctl_():
