Is it connected to a standard COM port? --David dkindred View Public Profile Visit dkindred's homepage! Find all posts by dkindred #3 September 8th, 2006, 08:49 PM MasterMog Seer Plus Join Date: Jul 2001 Location: Chattanooga, TN, USA Posts: 75 No, it was connected to a 4 port USB Serial Adapter as I don't have any standard serial ports available. I did try connecting to a standard port and the problem went away. I'm thinking that I need to purchase a different USB Serial Adapter. Do you know of a USB to Serial Adapter that people have had succcess running the AB8SS device?

The AB8SS has no buffer, so its timing needs are more critical than other serial devices. Anyone

TCP is one of the main protocols in TCP/IP networks. TCP is a connection-oriented protocol, it requires handshaking to set up end-to-end communications. Only when a connection is set up user's data can be sent bi-directionally over the connection. Attention! TCP guarantees delivery of data packets on port 8021 in the same order in which they were sent. Guaranteed communication over TCP port 8021 is the main difference between TCP and UDP. UDP port 8021 would not have guaranteed communication as TCP. UDP on port 8021 provides an unreliable service and datagrams may arrive duplicated, out of order, or missing without notice. UDP on port 8021 thinks that error checking and correction is not necessary or performed in the application, avoiding the overhead of such processing at the network interface level. UDP (User Datagram Protocol) is a minimal message-oriented Transport Layer protocol (protocol is documented in IETF RFC 768). Application examples that often use UDP: voice over IP (VoIP), streaming media and real-time multiplayer games. Many web applications use UDP, e.g. the Domain Name System (DNS), the Routing Information Protocol (RIP), the Dynamic Host Configuration Protocol (DHCP), the Simple Network Management Protocol (SNMP). TCP vs UDP - TCP: reliable, ordered, heavyweight, streaming; UDP - unreliable, not ordered, lightweight, datagrams.
