DigiWARE Release Notes PN 93000258E for DIGI_OS2 OS/2 Device Driver Version 1.37.3 IBM OS/2 2.11, Warp3, Warp4 Software P/N 40001479E Software Manual P/N 92000244B 10 Jan 2000 INTRODUCTION DIGI_OS2.SYS device driver for PCI bus intelligent adapters SUPPORTED PRODUCTS Digi PCI Xr, PCI Xem, PCI C/X, PCI EPC/X ENHANCEMENTS BUG FIXES 1. Fixed a problem where outstanding reads were not being flushed on the last close, causing some application programs to wait for a timeout period upon exit. 2. Added support for setting output DSR (ODSR) and DCD flow control (e.g: mode com3: 9600,ODSR=ON). Note that input DSR (IDSR) flow control is still not supported, and attempts to set it will be ignored. KNOWN LIMITATIONS 1. The current name convention supports "COM*" or "DIGI*" device names only. There is no current support for user supplied port names. 2. Altpin (as in the XALL.SYS driver) is not supported. 3. Set modem line signals are overridden by hardware flow-control; i.e: RTS and DTR are not changeable when flow control is set on (see dmode.exe for setting RTS and DTR handshaking.) 4. Instantanous error reporting is not supported. 5. Input DSR flow control (IDSR) is not supported and setting it will be ignored. HISTORY Version 1.37.2 29 March 1999 Fixed a problem where, in shared interrupt environments, interrupts generated by the digi_os2 driver could confuse other cards. Fixed a problem that caused the driver to crash on loading if more than 99 ports were allocated (e.g: /T:xx:43). Added support for PCI Xr-920 (2, 4 and 8 port) Fixed a problem where digidevf failed to recognize Digi adapters in slots associated with PCI Bus values greater than 0. Changed version to 1.4. Version 1.37.0 4 May 1998 Added support for PCI Xr-920 family (2, 4 and 8 port). Fixed fencepost calculation problem in the ioctl routine that checks to see if there are characters in the receive queue.
