File-Transfer Timeout
You can define the time the workstation waits for a response from the host system (in seconds). If the host system does not respond, the transfer is canceled, and an error message appears. A number in the range 20–65535 (or 0) can be specified. The default timeout is 30 seconds. Specify an appropriate value such that the error message does not appear too early. If you specify 0, a timeout is not set.
If a packet or block size is relatively large for low-speed lines, such as or COM port lines, it is recommended that 150 seconds or greater be specified.
