Release Notes: Windows NT ESP Driver


Note: Please note that the embedded esp firmware images (espapp.img, espboot.img, espbootb.img and espbootc.img) are no longer provided with the driver installation package. The embedded images are in a separate product that maybe downloaded from the Equinox website (see the "ESP Flash Components for Windows" package in the ESP section of the downloadable driver database).

Release Notes for Version 4.0.0.2

  1. Fixed IOCTL_GET_COMMSTATUS to return the stats collected from the driver for the ESP-8. A customer application would used the received chars number to read that many times and the driver would be out of sync where IRP_MJ_READ would return a len=0 at low baud rates.

Release Notes for Version 4.0.0.1

  1. Fix for a secure GPS application using the ESP-8 MI.

Release Notes for Version 4.0.0.0

  1. Changed branding from Equinox to Avocent.
  2. Added Avocent branded ESP-8 MI and ESP-16 MI models.
  3. Fix for old generation ESP-8 MI to get both RLSD and DSR events where there is an EPC_CS_DELTA for DCD.
  4. Added support for IOCTL_SERIAL_GET_STATS and IOCTL_SERIAL_CLEAR_STATS.
  5. Fixed two synchronous race conditions bugs in the driver that revealed themselves on the x64 with 4 processors.

Release Notes for Version 3.5.8.09

  1. Added ESP-4 MI support.
  2. Fixed the replace back button to not produce duplicates.

Release Notes for Version 3.08.05

  1. Fixed where if you enabled Auto Flash Update and then tried to Disable Auto Flash Update the ESP would still send the TFTP request for a Flash download.
  2. Added for a customer a private interface in espcfg.dll AutoFlashModeEx() that will allow them to automate the process of fixing ESPs that are in the field that are broke because of the above bug.
  3. Fixed the UpdateFlash dialog that was broke in multiple places with respect to the GUI, i.e. Going from Enable Auto Flash Update to Disable Auto Flash update the GUI would not present the saved entries for Auto Flash Update correctly and the same was true for Manual Flash Update.

Release Notes for Version 3.06.27

  1. EpcSendPending was not working correctly when we coalesce pending writes that will fit in a SendBuffer with IRP_MJ_FLUSH_BUFFERS.
  2. Fixed an issue when you unload the esp.sys all memory that was used by the esp.sys is now freed.
  3. EpcSendPending was not working correctly when we coalesce pending writes that will fit in a SendBuffer when the length exceeded the transmit window and we had to restart.
  4. Eqxloop.exe had a Dr. Watson error that occurred when you canceled out of the Properties Icon and selected the Restart Icon.
  5. Fixed an issue when you did a replace the esp property page showed defaults but the driver was using previously changed values that had been changed by the user.
