- SIO2K Beta Revision history
-
- 02/25/98 - Beta 003
- First public release.
-
- 02/26/98 - Beta 004
- The bit rate was being set incorrectly on most uarts. This
- problem was corrected. The text file techtalk.txt was added
- to the distribution files.
-
- 03/06/98 - Beta 005
- Support added for the 16850 uart. Except for the size of
- the fifos, this chip seems every bit the equal of the Hayes
- ComBic (used on the ESP) that I like so much.
-
- At this time, I cannot add support for the 16952. The chip
- seems to have a bug that is difficult for me to work around.
- Working around the bug would severely impact the performance
- of other uarts. I have reported the bug to Oxford
- Semiconductor. I can support the 16952 with a special
- interrupt service routine, but that is going to take time to
- write.
-
- Fixed a problem in vsio2k.sys so that it would not
- unnecessarily open serial devices during session
- initialization.
-
- Fixed a problem where RTS would not be turned on for 16650
- UART.
-
- Fixed a problem with the 64 byte FIFOs of the 16750.
-
- Crystal frequency was being incorrectly calculated for x2
- devices. This has been corrected.
-
- 03/17/98 - Beta 006
- Corrected a problem where the IRQ could not be automatically
- detected when a series of UARTs shared the same IRQ.
-
- Automatic IRQ detection is now only done once.
-
- Automatic IRQ detection is skipped for PCI devices as the
- IRQ is known.
-
- The read function incorrectly returned an error 8111 (hex)
- at times. The problem has been corrected.
-
- Somewhere along the line of changes, the transmit load count
- was corrupted. This meant that only one character was being
- transmitted per interrupt. This problem has been corrected.
-
- The code to support the 16650 and 16650A was severely
- corrupted in the beta 005 release. This has been corrected.
-
-
-
-
-
-
-
-
- Xon/Xoff flow control on UARTS with built in flow control
- was not being set correctly in previous versions, and is now
- corrected.
-
- 03/30/98 - Beta 007
- Added support for the GTEK JetPort PCI cards.
-
- Added Resource Manager (aka Hardware Manager) support.
-
- Detection of SMC SuperIO motherboard uarts is now done at
- boot time instead of at "first touch" time.
-
- Corrected a bug in VMODEM.EXE that caused it to trap (at
- program exit) on some systems.
-
- VMODEM.EXE displayed the wrong COMn name in log messages.
- This has been corrected.
-
- Corrected a problem is ESP.SYS that would cause a
- system hang if an ESP port was used in compatibility
- mode following its use in enhanced mode. Note that
- once an ESP port is used in enhanced mode,
- compatibility mode will not work again until power is
- cycled on the computer. I do not know why, that is
- just the way it is.
-
- Bit rates above 115200bps was not being set correctly on SMC
- SuperIO (motherboard) UARTS. This problem has been
- corrected.
-
- Corrected a second problem in ESP.SYS that would cause
- system hangs.
-
- If a system had more than one PCI bus, the same board would
- be detected twice. This problem has been corrected.

-
- 05/11/98 - Beta 008
-
- If no config file was used (sio2k.cfg) then PCI devices were
- not being completely initialized. This problem has been
- corrected.
-
- Incorrect status was being returned (at times) from IoCtl
- function 64h. This problem has been corrected.
-
- A problem with shared IRQs on PCI devices has been
- corrected.
-
- A problem that caused lockups (continuous interrupts) using
- PCI devices has been corrected.
-
- The 16850 and 16950 was not being reset correctly at device
- close. This problem has been corrected.
-
- A problem in the implementation of the Os2Shares config file
- option has been corrected. This error prevented some DOS
- apps from being able to access a port.
