Hi All
    I'm trying to use TCP4U, I've got it all working both sending and
receiving data (on the backchannel) , the send fuction is fine, however if I
try receiving more than one byte at a time I get an error

sock_receive = tcp4u_receive(sock, 1, 1)
         if sock_receive[tcp4u_ret] = TCP4U_SUCCESS then
--   code snipped
         else
              appendText(IPDS_RE,sprintf( "\n tcp4u_receive error '%s'\n",
{tcp4u_error_string(sock_receive[tcp4u_ret])} ))

-- works fine but slowwwwly

But
sock_receive = tcp4u_receive(sock, 1000, 1)
       if sock_receive[tcp4u_ret] = TCP4U_SUCCESS then
--    code snipped
           else
          appendText(IPDS_RE,sprintf( "\n tcp4u_receive error '%s'\n",
{tcp4u_error_string(sock_receive[tcp4u_ret])} ))

-- gives me an error of 'Not a TCP4 return code'

    I've tried this on both W2K and XP, I do not need to do anything wth the
received data, I just want to clear the other devices buffer..
it's bound to be something I am doing wrong.... Has anyone got any
suggestions?

Pete.
