PSC 315 manual Patch version a

Introduction

Patch version A 09-07-05

This change will cause the DOS emulators to use a random source port between 2000 and 2100 on each outbound host connection.

Prior to this, they used the same source port number and this would cause problems with some IBM hosts and Firewalls. This would lead to long timeout periods (5-30 minutes) on IBM hosts and lockouts under Firewalls that looked at this as a possible denial of service attack.
