It requests a control server to send SIGUSR1 to the engine. The control server should immediately reply an acknowledgment to the client.
|int32 OX_COMMAND||int32 SM_control_reset_connection|
All engines are encouraged to install the reset protocol,
but when it is not implemented,
no_ox_reset option should be included in the fourth argument
(option list) of the mathcap (ref: oxpari).
Note: Some old implementations of control servers and clients (before 2000)
assume the result code of the following format.
These obsolete implementations should be updated.
|int32 OX_DATA||CMO_INT32 result|
It requests a control server to terminate the engine and the control server itself. All files and streams should be closed before the termination of servers.
|int32 OX_COMMAND||int32 SM_control_kill|
Example: (serial numbers are omitted.)
0 0 2 01 (OX_COMMAND) 0 0 4 06 (SM_control_reset_connection)
OX_SYNC_BALL are exchanged on the data channel for synchronization.
