On mramx1.rsma.frb.gov, I create a master socket connection:
> server <- socketConnection(port = 11223, server = T, blocking = T, open =
> "a+")
This does not return until I connect with a client from another machine:
> client <- socketConnection("mramx1.rsma.frb.gov", port = 11223, open = "a+")
Now, back on the first machine, I do this
> writeLines(paste("line ", 1:3), server)
and on the client,
> readLines(client)
[1] "line 1" "line 2" "line 3"
All well and good. But if I try writing back from client to server, it
doesn't work. Still on the client machine, I do this:
> writeLines(paste("line ", 1:4), client)
but back on the server, this hangs the R process
> readLines(server)
I've also tried this with blocking = F on the server with the same result.
What am I missing?
