SST Driver for BSDI

Release Notes: SST Driver for BSDI

Installation Instructions

The self-extracting driver file includes Help (.hlp) files to assist you in installing the driver.

The zip download file is in a "dd - compressed" UNIX file format. You must run "uncompress" then "dd" the file to a floppy device to create an installable diskette. View BSD_DNLD.TXT for additional installation information.

Note: Equinox does not provide free BSD support.

Use with BSDI OS Versions 3.0 and higher on AT-ISA/EISA & PCI Bus Type platforms.

To install this Device Driver - mount floppy with "mount -o rdonly /dev/fd0 /a" command. Then use "installsw" command and follow menu prompts. You must know your bsdi kernel config file name & I/O address if installing a SST ISA serial card.

Release Notes

Version 3.36

Adds support for the following new SST products:

• SST-4I,PWR
  
  
• SST-8I,PWR
  
  
• SST-4P,PWR
  
  
• SST-8P,PWR
  
  
• Corrects an error in the timing window initialization logic that could cause some ports on SSP4-based boards to operate incorrectly.

Version 3.35

• Added support for new 4 and 8 port PCI RJ boards: SST-4P/RJ and SST-8P/RJ
  
  
• Removed support for BSDI rev 2.1 objects
  
  
• Added support for BSDI 4.0 objects
  
  
• The TIOCSDTR, TIOCCDTR, TIOCMBIC, TIOCMBIS, and TIOCMSET ioctls now set/clear both the standard control signal as well as the overload control signal. Previously, they set only the standard control signal. This could result in incorrect behavior when in an input overload (flow control) state.
  
  
  • The TIOCMSET ioctl now clears those signals which are not specified. It previously only set those bits requested.
    
    
  • These ioctls will not allow a signal being used for flow control to be programmatically altered (e.g., a request to change the state of RTS will be ignored if CRTS_IFLOW is enabled).

Version 3.33

• The driver now enables the 16-byte FIFO buffer on modem boards that use the 16550 UART (e.g. USR 56KB modems). This change increases the reliability of such modems.
  
  
• A fix was made to preclude a rare condition that can cause a port to hang when TAB3 is enabled. This potential problem was discovered during testing at Equinox.
  
  
• Added support for two SSp4 events: input overflow and lost data. This fix precludes a situation that could cause a port to hang when the SSP buffer is overflowed after RTS is dropped. The overflow is now detected and results in port being flushed and restored to working order.
  
  
• A modification was made to allow the driver to recover the expansion bus in certain situations that previously required human intervention. In past releases, Modem Pool events were ignored due to the possibility of false events. The modification uses the bus on-line status to determine if the Modem Pool is really off-line when an event occurs; in such cases, the event is now processed.

Version 3.32

• Integrated new modem pool services that enable certain PnP modems to now function properly (these modems take longer to init).
  
  
• Fixed a regression introduced in an earlier release that broke BRKINT processing for non-modem pool ports.
  
  
• Added scanning for parity errors and framing errors. This should also allow break processing on modem pool ports.
