SYMPTOMS

When you use code page 870 as your host code page with the 5250 Applet, incorrect characters are sent and received to/from the host.

CAUSE

The 5250 Applet that is delivered with SNA Server uses OEM code page 852 to convert American Standard Code for Information Interchange (ASCII) to Extended Binary Coded Decimal Interchange Code (EBCDIC) characters or vice versa, rather than using code page 1250.

RESOLUTION

To resolve this problem, obtain the latest service pack for SNA Server 4.0. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS

Microsoft has confirmed that this is a problem in Microsoft SNA Server version 4.0 (all Service Packs).

This problem was first corrected in SNA Server 4.0 Service Pack 4.

MORE INFORMATION

When you encounter this problem, you may see the correct characters displayed in the 5250 Applet when you are typing.

Before these data are transferred to the AS/400, ASCII to EBCDIC conversion is performed. Because the 5250 Applet is a Microsoft Windows application, code page 1250, Windows Latin 2 (Central Europe) must be converted to EBCDIC code page 870, instead of code page 852, MS-DOS Latin 2 to EBCDIC code page 870.

Therefore, the data arriving at the AS/400 are mapped to incorrect EBCDIC characters. This problem affects both Polish and Czech customers.
