CONNECT integer-variable, string-expression, integer-expression

Opens a TCP connection.

First parameter: an integer variable (created if it does not yet exist).
On success it will be set to a non-negative handle that you then pass to SOCKREAD, SOCKWRITE, and SOCKCLOSE.
Second parameter: a string containing the IP address to connect to.
To resolve a hostname into an address string, use DNS$.
Third parameter: the port number (integer expression).

On failure, an error is raised.

Example: connect, send, receive, close

HOST$ = DNS$("example.com")
CONNECT H, HOST$, 80
SOCKWRITE H, "HEAD / HTTP/1.0" + CHR(13) + CHR(10) + CHR(13) + CHR(10)
SOCKREAD H, REPLY$
PRINT REPLY$
SOCKCLOSE H

Notes

The first argument must be an integer variable, not a literal or expression.
Always close the handle with SOCKCLOSE when finished.
SOCKREAD is a blocking operation; see its page for how to cancel with CTRL+ESC.
