Table 4-2. Exchange/RJE Line Server Errors (Page 1 of 2)
Standard Error Messages
0 No error occurred; the operation completed successfully.
1 An EOF was read, or an ETX was received from the remote system.
2 You have attempted an operation that is not allowed on the type of file you specified.
12 The file you specified is in use. Wait and try the operation later.
16 The file you specified has not been opened yet. The file must be open before you can
perform I/O operations on it.
21 You specified a value that is out of range. Typically, this means that the number of bytes
to transfer in an I/O operation is too large or too small.
28 This operation would exceed the number of outstanding nowait I/O operations allowed on
the specified file. For the Exchange/RJE line server, only one outstanding nowait I/O
operation is allowed.
40 The time limit you specified in the AWAITIO call elapsed before the I/O operation
completed. This can also indicate other file-system timeout errors.
60 The mounted volume does not contain the specified file, or the device was down and then
was brought back up before the I/O operation completed.
66 The device is down.
70 Ignore message and continue normal processing.
140 A modem error, such as an unexpected loss of the carrier detect (CD) signal, occurred.
156 An I/O process protocol error occurred.
157 An I/O process internal error occurred.
160 You have attempted an operation that is not allowed in the current state of the line. For
example, you have attempted to initiate a send operation while the remote system still
controls the line.
161 An event has been detected that is not allowed in the current line state.
162 The attempted operation timed out after the specified number of retries. The number of
retries is specified for the data communications line during system generation.
163 An EOT was received from the remote system.
164 A DLE EOT (disconnect) was received from the remote system.
165 An RVI (reverse interrupt request) was received from the remote system.
166 An ENQ (inquire) was received from the remote system.
167 An EOT was received during a bid for the line. The bid was rejected.
168 A NAK (negative acknowledgment) was received during a bid for the line. The bid was
rejected.
169 A WACK (wait before transmitting acknowledgment) was received during a bid for the line.
The remote system temporarily cannot accept the bid.
171 A reply was expected and the remote system did not respond.
172 The remote system’s reply was not a valid response within the BSC protocol.
173 The maximum number of NAKs was sent. The transmission from the remote system was
unable to be completed without an error.
