ABORT Command The ABORT command stops a send or receive operation.
A[BORT]
Line Activity The ABORT command sends an EOT (end of transmission) character to the remote
system. This tells the remote system that the local system is unable to continue the
operation. In the case of a receive operation, the remote system may or may not stop
sending data depending on how it is programmed.
Considerations The ABORT command stops the current send or receive operation. Use this command
to stop a send or receive operation before it completes normally.
Generally, an ABORT command is followed by a RECEIVE command with the ALL
parameter specified as shown below.
>RECEIVE JUNK, ALL
The purpose of this RECEIVE command is to accept any output that the remote system
may attempt to send. By accepting this output, you can place both the local system
and the remote system in a known state with no extraneous output waiting to be sent.
This ABORT command followed by the RECEIVE command also handles the case
where you attempt to stop a receive operation but the remote system ignores the
request to stop and continues sending data.
If no send or receive operation is outstanding, the ABORT command is ignored and an
error message is displayed.
You can use the STATUS command to see the status of the current send or receive
operation, if any. See the STATUS command later in this section for more information.
