1. Enhancements
- Expanded EBIOS support in INT 14h Function 0h, Initialize a
Port. See Manual Errata.
2. Limitations
- The driver's INT 14h interface is not 100% compatable with the
the following DOS drivers and their supported boards:
xapcm232.sys - PC/X*, xim232mc.sys - MC/Xi, and xim232.sys -
COM/Xi. If you are using an INT14h application for an earlier
driver, compare the driver's INT 14h specifications to
determine if any of the incompatabilities may affect your
application.
3. Bug Fixes
- Fixed bug in xidoscfg.exe. On the MC/2e board, when the IRQ
was disabled using the POS configuration utility, xidoscfg.exe
would display an erroneous IRQ number on the driver config-
uration screen.
4. Manual Errata
- Please note that the DOS driver files are no longer found in
the root directory of the release diskette, but located in
the DOS directory. Any manual references to the files being
located in the root directory is in error.
- Expanded EBIOS Support
Under the EBIOS specification, the highest baud rate
accessible is 19200. The function was enhanced to provide
access to 38400, 57600 and 115200 baud rates. For the
programming interface see INT14.TXT. This enhancement was
made to permit access to higher baud rates from INT 14h
based communication programs that only provided selections
of up to 19200. The driver was changed so that when EBIOS
support is selected from the XIDOSCFG.EXE configuration
utility, the following baud rate substitutions are made :
4. Manual Errata (continued)
110 -> 19200
150 -> 19200
300 -> 38400
600 -> 57600
1200 -> 115200
2400 -> 2400
4800 -> 4800
9600 -> 9600
So, for example, to access 57600 support, select EBIOS
support in XIDOSCFG.EXE and select 600 baud in your
communication program.
