Introduction

A C32 plug-in that provides serial port emulation over a TCP socket. The socket can be configured to either actively connect to its TCP peer, or to passively listen for a connection from the peer.

Configuration

Configuration of the ports is done via the Central Repository file 102836da.txt. This is expected to contain the following key space:

 Bits    Supported Values    Meaning

 31-24   0                   Port record. Port fields assigned as follows:
 23-16   0                   Socket mode (type int, 0 - active, 1 - passive)
         1                   Protocol family (type int)
         2                   Protocol (type int)
         3                   IP address (type string in valid form to be handled by TInetAddr::Input)
         4                   Port (type int, the port to connect to in active mode or the port to
                             listen on in passive mode)
 15-0    0-65535             C32 unit value

For example:

 # Port 0
 0x00000000     int     0               # Active socket.
 0x00010000     int     0x0800          # KAfInet.
 0x00020000     int     6               # KProtocolInetTcp.
 0x00030000     string  127.0.0.1       # IP address.
 0x00040000     int     3030            # Port.

 # Port 1
 0x00000001     int     0               # Active socket.
 0x00010001     int     0x0800          # KAfInet.
 0x00020001     int     6               # KProtocolInetTcp.
 0x00030001     string  172.16.0.2      # IP address.
 0x00040001     int     3030            # Port.

Note, the Central Repository file can be written to by any process with WriteDeviceData capability. It is therefore possible to dynamically add new, and alter existing port configurations.
