Host-Initiated Connections
Using the MSS
5 - 4
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 port’s 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.
NOTE:
To ensure that the port will be idle, do not attach a terminal to
the serial port to issue the socket connection command.Telnet
to the remote console port instead.
•
Only one serial port connection is allowed at a time.
•
Timing and serial signals are not preserved.
5.1.4 Code Examples
The MSS distribution CD-ROM includes examples of code for TCP/IP
and SPX/IPX applications. Refer to the Readme file included with the
code examples for further information and instructions.
