There is some router equipment on the Internet that does not generate proper responses when an MTU size needs to be adjusted; this may cause connections to hang. For this reason, SCO has disabled this feature for this release.
If you wish to enable this feature, enter the following commands
/etc/inconfig tcp_offer_big_mss 1
/etc/inconfig ip_perform_pmtu 1
