Assume a VT-100-type terminal accessing a UNIX host in the following ways:
(1) via a TCP/IP terminalserver networked with the target host
(2) via an asynchronous line interface integrated in the target host
There is a significant difference in how a BREAK (CTRL-C) condition is
In case (1) the terminalserver (3Com/Bridge LS/1, Cisco xSM) continues to
empty its buffer towards the terminal.
In case (2) the output to the terminal stops immediately.
On a UNIX system, try to cat /usr/dict/words with the two attachments
described above. In case (1) tens, hundreds of pages will be displayed
after hitting BREAK (or ^C), which is considered a problem of acceptance.
What is the reason of this different behavior? Would there be no way to
"rollback" the current buffer's worth of packets upon receiving a BREAK
and just flush the buffer?
Thanks in advance for any comments.
