Previous Version: 1.2.0


Description of Change or description of new product:
****************************************************


I) Changes to driver:

Corrected problem affecting write of data to port when buffer was in "himem".

Corrected problem with corruption of "temporary memory selector" during 
download process.  This change should eliminate the reported problem of 
"the driver hangs during initialization."

Added command line option /Z to permit a DOS-style "sticky DTR signal" mode of 
operation.  When active the DTR signal is not automatically dropped during 
the close of the port.  The default is for this mode to be inactive and for 
the ports to operate in normal OS/2 mode.  The syntax is:
/Z:1  -- activate "sticky DTR" mode
/Z:0  -- don't activate "sticky DTR" mode, which is the same mode as when 
the option is omitted.
This option affects all the ports.  It can only be set by the DEVICE= line 
in the config.sys file.  The state of this option cannot be queried or changed 
programmatically by any means (not even AMODE.EXE)  This option is provided for a specific customer.  It has no general interest for anyone else.  

ECO#: 505029


II) Changes to Manual:

 Changes to pages 9 and 12 of section 3.


NOTES: 

1) Manual 92500003A will have to be updated before the next production run. 
   This version can ship until depleted.
