R help - Dec 2008 - Writing a Long across the network?

Hello,
	I have to write  single Long to a server written in java. The server  
passes the input as
	
	in.readLong() // it expects to receive 8 bytes

	In Python, i can do it by sending struct.pack( "!q", value)

	However, I have tried this
	writeBin(length(x),con=conn,endian="big") #conn opened in binary

	But the response on the server side is wrong, eg. 1 is received as  
4294967297

	How do I then write  long across the network from R?

	Thank you
	Saptarshi

Tell writeBin() the 'size' you want: see its help page.
