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 is 60 seconds for ASCII sessions; for all others, it 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 COM port lines, it is recommended that 150 seconds or greater be specified.
