Using the MSS Incoming Connections
5 - 3
NOTE: The procedure is similar for DEC UNIX LAT.
If heavy input or output loads are expected on the LTA port, you can set
alternate type ahead to reduce ßow control on the ports.

To connect to the MSS serial port from a VMS host, use the command below
and include the appropriate LAT application port number:

5.1.3 Host Applications
The MSS can be used with applications on Unix, Windows, Windows NT,
OS/2, LAT, and Macintosh hosts, and any other hosts that have a TCP/IP or
SPX socket interface.
When a host application makes a socket connection to the MSS, it uses the
socket as a data pipe to send and receive data. The host application performs
general read/write tasks, and works with the MSS as if it were a directly-
attached serial device.
There are some important points to remember when making a socket
connection.
¥ Port access must be set to either Dynamic or Remote to allow network
connection requests. Local access does not allow a port to receive
connection requests from the network. To change the portÕs access
type, use the Change Access command followed by either Dynamic or
Remote.
¥ The port must be idle. Use the Show Ports command to verify that the
port is not in use. To ensure that the port will be idle, Telnet to the
remote console port rather than attaching a terminal to the serial port.
¥ Only one serial port connection is allowed at a time.
¥ Timing and serial signals are not preserved.
