Data acquisition from DECserver via IP?

» close window

The Question is:

RAW TCP listener for DECserver 90M
We are currently using DECserver 700 with LAT. The application that runs on
 Open VMS alpha is essentially a data acquisition program that scans/polls
 serial devices and modems attached to terminal server ports. The application
 performs host initiated LAT
connections and uses QIO system services to perform input/output.
We are planning to move our termianl servers from LAT to TCP/IP only. For this
 pilot we are using DECserver 90M running TCP/IP. I was able to setup RAW TCP
 listener on DECserver 90M port, and was able to establish host initiated
 connection to this port us
ing socket calls from the test program. I was also able to send data request to
 this port from the test program running on OpenVMS host. However, I was not
 able to get /read the terminal server  response to the data commands over the
 same socket. I would
really appreciate any information on how to perform raw TCP input/out on a
 terminal server port.
Thanking you in advance.

The Answer is :

  Please see the existing discussions of "reverse telnet".
