timeout

The timeout command lets you set the amount of time that can elapse before a file transfer packet is re-sent because it wasn't acknowledged (an event known as a "retry"). Set the timeout with the command:
 
timeout number

where number is the number of seconds that can elapse without receiving an expected packet (such as a packet of data or an acknowledgment).

The timeout value normally defaults to 10 seconds. This should work fine with most file transfers. You may need to make the timeout value longer when transferring files with a slow or overburdened system, when using YMODEM or XMODEM file transfer commands, or when transferring files over a packet-switching network. The symptoms of a timeout value that is too short are excessive retries and excessive "retries exceeded" file transfer failures.

The timeout setting affects these file transfers:

transmit and receive     ytransmit and yreceive     xtransmit and xreceive
ztransmit and zreceive   ygtransmit and ygreceive   xgtransmit and xgreceive

Note The YMODEM-g and XMODEM-g commands don't exchange acknowledgments during the course of a file transfer, only at the beginning and end. The timeout therefore has minimal effect on these file transfers.
