Virtual Terminal

Reverse Virtual Terminal

Because the VTERM option is speciﬁed, the application program

communicates with the remote terminal by way of the Virtual Terminal

rather than by way of Remote File Access. In both VT and RFA, the

remote terminals function as non-session I/O devices. With RFA, you

have to create a remote session on the node where the terminal resides.

With Reverse Virtual Terminal, however, the application program does

not establish a remote session on the node where the terminal resides.

The terminal users cannot call subsystems or issue commands to the

remote system. A privileged mode program can communicate with the

terminal in nowait mode by setting bit 4 in the FOPEN aoption

parameter. The application program will not recognize a

[BREAK] or

[CTRL]-Y issued from the remote terminal’s side of the connection.
