The Question is:
This is an industrial application that runs on OpenVMS Alpha system. It
essentailly gathers real-time data from various industrial instruments,
some of them are connected directly to DECserver 700 serial ports and
others via modems attached to DECserver ports. The application uses
QIO system services for these LAT devices. The management is planning
to move from LAT to TCP/IP based terminal servers. My question is how
do I access devices attached to terminal servers in TCP/IP environment?
Can I issue host initiated connection requests to the terminal server
ports?
The Answer is :
TCP/IP lacks some of the capabilities of LAT in this environment.
Please see the existing discussions of Reverse Telnet for how to
establish an outbound connection -- depending on the particular
terminal server, you may well end up using other approaches to
communicate with the device.
