You could try setting the tcp_keepidle to something lower like 1200 and the tcp_keepintvl to something higher like 300 and the tcp_nkeep to something higher like 24
These parameters are set at boot time in /etc/default/inet ("man inconfig" will tell you what file contains the parameters for your OS version)
You can set them live using inconfig - look at the man page for inconfig; something like this would only change the parameter until the next boot:
inconfig -n tcp_keepidle 1200
inconfig -n tcp_keepintvl 300
inconfig -n tcp_nkeep 24

You don't give a lot of information. Check the "keep-alive" setting, in Tiny-Term, doing so will prevent the session being dropped if the server gets busy.
