Have a look in the dictionary at the tsNetSetTimeouts command. In particular, the last two parameters allow you to define a minimum transfer speed so that if a transfer falls below that speed, tsNet will abort the connection.
For example, if you issue the following command: tsNetSetTimeouts 30, 0, 300000, 60000, 30, 10000 Then tsNet will abort any connection that is transferring at a rate slower than 10000 bytes per 30 seconds.
