Summary:
To function correctly under Windows Version 3.00 386 Enhanced mode, DCA 10Net networks require the following switches in the [386ENH] section of the SYSTEM.INI file:
UniqueDOSPSP=yes PSPIncrement=1 <or higher; see below>
Depending on the specific hardware and software configuration being used, the value for PSPIncrement= may need to be varied.
More Information:
10Net networks use PSP (Program Segment Prefix) addresses. It is critically important to their proper operation. If you have two DOS applications running on 10Net in different virtual machines and the applications have the same PSP address, one of them will crash the other one when it exits.
The UniqueDOSPSP=yes switch is used to enable or disable PSP address adjustment in virtual machines (for correct network operation on networks that use the PSP address).
The PSPIncrement switch is used only when UniqueDOSPSP=yes. It sets the amount of the PSP adjustment made for each virtual machine. The default is 1 (paragraph). Note that the valid range for this is 1-64, inclusive. Numbers less than 1 will set the value to 1, numbers greater than 64 will set the value to 64.
