CLIENTSOCKET

CLIENTSOCKET

This function creates an outgoing TCP connection or sets up UDP transmissions. Once set up for UDP, packets can be sent by printing to the socket. Packets are sent when the size limit is met or a
EOT
 character is written.
Format
CLIENTSOCKET (TYPE$, IPADDR$, PORT)
Parameters
  • TYPE$
     = set to "UDP" or "TCP".
  • IPADDR$
     = connects to this address.
  • PORT
     = connects to this IP port.
Returns
The port number assigned to the connection.
Example
See the examples for TCP Server and UDP Server.
Comments
Multiple communications connections can be made up to the maximum of 10. Each protocol may have a different limit based on the support of the print server used. Test the worst case situation based on your application’s needs or use
ONERROR
 to recover from failed connection attempts.
