Purpose

Receive data from a specified TCP/IP port.

Syntax

TCP RECV [#] fNum&, count&, Buffer$

Remarks

Receive count& bytes from the fNum& TCP/IP port and place them in Buffer$. If count& bytes are not available, Buffer$ will receive whatever bytes are available and EOF(fNum&) will return TRUE (non-zero).

Typically used in a loop to retrieve a stream of data, a TCP RECV loop should be terminated if Buffer$ returns an empty , or if EOF(fNum&) returns TRUE, or if ERR becomes set. If a time-out occurs, ERR will be set to indicate a run-time Error 24 ("Device timeout"). See TCP OPEN to specify the TCP socket timeout value.
