TCP-Com from TAL Technologies is a Windows-based software
utility that is designed as a RS232 to TCP/IP converter.
TCP-Com performs two jobs:
1) It exposes the physical serial ports on a PC to TCP/IP
network ports.
2) It can now also create "Virtual COM Ports" that
are actually connections to a TCP/IP port.
TCP-Com therefore allows you to send and receive RS232 (serial)
data across any TCP/IP network including the Internet.
The latest release of TCP-Com (version 4.1) now has support
for the User Datagram Protocol (UDP) in addition to TCP/IP.
The UDP protocol is similar to the TCP/IP protocol except
that the TCP/IP protocol is a "connection" protocol
whereas UDP is a "connectionless" protocol. With
TCP/IP, a client application establishes a connection to
a TCP/IP Server and data is exchanged until the connection
is closed by either the client or the server. You can think
of it as similar to a telephone connection where the client
dials the connection to the server and they carry on a conversation
until either party hangs up the phone. With UDP, both the
client and the server open the same "port" and
when one sends data, it is received by the other however
there is no actual "connection" between the client
and the server.
In contrast to TCP/IP, the UDP protocol works in a manner
that is analogous to two walkie-talkies that are tuned to
the same channel. With TCP/IP, if a CLIENT tries to establish
a connection to a SERVER that is not available, then the
client receives an error indicating that no connection is
available. With UDP if there is no server, the Client does
not receive an error. Also, with TCP/IP communications, if
either end sends data to the other end and the data does
not get through, the sending application receives an error
indicating that the data transmission failed. With UDP communications,
no error checking is performed therefore data is not 100%
guaranteed to get through. However, UDP communication is
generally much faster than TCP/IP. UDP also recovers more
easily if there are failures in a network connection that
are subsequently repaired.
