DigiWARE Release Notes 93000241C for DigiCHANNEL PC/X*, COM/Xi, MC/Xi, Xem, C/X, EPC/X and PC/Xr Universal OS/2 Device Driver XALL.SYS V1.5.4 Diskettes P/N 40001479C (3) Software Manual P/N 92000244C 4 May 1998 Below are Enhancements and Bug fixes made to XALL.SYS V 1.5.3 resulting in the new XALL driver V 1.5.4 Enhancements Bug Fixes 1. Added a 1 second init time delay to allow slow cards to load properly. Known Limitations 1. If there are multiple cards in the system and one has an init- ialization problem, none of the cards will work. The driver de-installs. Manual Errata 1. A new config.sys switch exists enabling the user to modify the default parity error detection scheme used by the Digi board. The switch is /E: . Valid parameters are: C - Check parity errors D - 16450 mode parity error marking (DOSMODE) I - Ignore parity errors (i.e. error characters discarded.) M - Mark parity errors A switch with no parameters turns off all parity error detection. The default setting of 16450 parity error marking is used if no switch is used. Examples: /E:MCD - Mark parity errors using 16450 method (DOSMODE). This is the default and is the same as no switch used. /E:I - Ignore parity errors. Error characters are discarded. /E: - Turns off all parity error checking. This is the most efficient mode.
