Bitfields for PCIBM PC/TCP(Transmission Control Protocol) A higher level (session layer) of the TCP/IP protocol suite.  See also IP, TCP/IP. receive options:
Bit(s)	Description	(Table 03465)
 1	do not remove data from queue, just copy it
 2	do not copy data, just remove it from queue
 5	fail if datagram would be truncated
 6	do not block, return error if no data available
Note:	special case for UDP: if both 1 and 2 set, return number of datagrams
