- WHAT'S NEW IN KSP SLIP
-
-
- 3.2: Clean Up: Redesigned as multi-threaded code using the MIX
- Multi-C library.
-
- Clean Up: The inactivity timer was being restarted
- everytime a character was received on the serial line, and
- thus noise could sometimes keep the timer from reaching
- zero. Now the timer is only restarted upon receipt of a
- error-free inbound slip packet.
-
- 3.1: Clean Up: Improved handling of "ksp-slip.ophours" . If
- start time is after the stop time, the hours of operation
- will be interpreted as all but those in the window
- specified. I.e., setting ophours to 03:20-03:00 will
- allow operation anytime except 03:00-03:20.
-
- 3.0: New Feature: Added a option (ksp-slip.blocked_ip_list) to
- specify the name of a file containing a list of blocked IP
- addresses. Users will not be allowed to connect to any IP
- address on this list, and a TCP/IP ICMP type 3 (host
- unreachable), code 10 (communication with destination host
- is administratively forbidden) error notification packet
- is sent to the user's SLIP client.
-
- 2.9: Bug Fix: If the minutes remaining passed to KSP-SLIP in
- the DOOR.SYS file was zero, the user would get unlimited
- time; corrected.
-
- 2.8: Work Around: Discovered that the ARNET driver in Egberto
- Willies' COMM-DRV (used by Clark Development's PCBoard)
- does not adhere 100% to the fossil spec in that function
- 04h (Initialize) does not return 1954h when called with
- DX=00FFh. I was using this to detect the presence of a
- fossil driver as recommended in the fossil spec! Corrected
- by modifying the presence test to add two additional
- presence tests if the first one (04h) fails.
-
- 2.7: Bug Fix: Fossil drivers do not typically detect an
- incoming serial "break" signal. Thus when used with a
- fossil driver, the configuration parameter called
- "serialport" is used to enable additional code to provide
- this feature. Although this code worked fine when tested
- with the X00 fossil driver, it prevented both the BNU
- fossil driver and PCBoard's COMMDRV program from doing
- serial output properly. Corrected.
-
- Bug Fix: Was not detecting carrier loss (user hangup)
- properly. Corrected.

- WHAT'S NEW IN KSP SLIP
-
-
- Clean Up: When opening the door, the number of minutes
- remaining is displayed properly to the caller. However,
- the minutes remaining was not tracked properly while
- running the door when it was a very large number (like
- 1440 minutes = 24 hours). Corrected.
-
- 2.6: Bug Fix: Wasn't working with Digiboard when used with a
- fossil driver. Corrected.
-
- Bug Fix: Configuration parameter
- ksp-slip.serialport=<adr>,<irq> was not working properly;
- corrected.
-
- Bug Fix: The COM port number in DOOR.SYS was limited to
- COM1 through COM4 since this is all that can be supported
- by the async library; however, there should be no such
- limit if a fossil driver is used. Corrected.
-
- Bug Fix: The special break detect code used with fossil
- drivers was interfering with normal fossil operation;
- corrected.
-
- New Feature: Added support for an environment variable
- (ksp-ip) to set the IP address. Since the IP address is
- often the only parameter in WATTCP.CFG that changes from
- one BBS node to another, this allows using a single copy
- of that file for all nodes.
-
- Clarification: Some Internet access providers configure
- their dial-up slip and ppp accounts with a very small
- segment size. You may need to set mss as low as 212 if
- your Internet connection is through such a connection.
-
- 2.5: Oops! When I fixed the search algorithm in 2.5, I
- accidentally broke the "include" directive in WATTCP.CFG.
- Corrected.
-
- 2.4: Bug Fix: Dynamic parameters did not function properly;
- corrected.
-
- Change: Changed the search order for WATTCP.CFG to be
- downward compatible with earlier versions of KSP-SLIP.
- First, it checks for an environment variable called
- WATTCP.CFG that specifies the directory. Second, it looks
- in the current (default) directory. Third, if still not
- found, it looks in the directory that contains the
- executable (KSP-SLIP.EXE).
-

-
-
- 2.3: New Feature: Added a command line option (e.g.,
- /MAX_MINS=60) to limit the time a caller is allowed in the
- door. If used, time in the door will be the minimum of
- that specified by the option and their time remaining on
- the BBS.
-
- Enhancement: KSP SLIP now looks in three directories to
- locate the WATTCP.CFG configuration file. First, it
- checks for an environment variable called WATTCP.CFG that
- specifies the directory. Second, it looks in the
- directory that contains the executable (KSP-SLIP.EXE).
- Third, if still not found, it looks in the current
- (default) directory.
-
- Enhancement: Added a command line option
- (/CONFIG=<number>, where "<number>" is a non-zero integer
- such as "1") to facilitate dynamic configuration options.
- If used, then any WATTCP.CFG configuration file parameters
- of the form:
-
- ksp-slip[<number>].<parameter>=<value>
-
- are ignored unless the integer number enclosed in square
- brackets matches that specified in the command line
- option. This also works for global parameters, such as
- "ksp[<number>].<parameter>".
-
- 2.2: Bug Fix: KSP SLIP was sometimes hanging on exit because it
- had not unhooked the serial port interrupt routine before
- exiting the program. Corrected.
-
- Bug Fix: There is a special end-of-frame marker that
- identifies the end of each slip packet. A common practice
- is to also send one of these at the beginning of a data
- packet so that the receiver will see an empty packet
- followed by the (real) data packet; this helps the
- receiver tolerate line noise by effectively telling it to
- flush its input buffer in preparation for the arriving
- data. A common performance enhancement is to eliminate
- the extra empty packet if it falls "on the heels" of the
- previous data packet; it would be redundant since the
- receiver will have just flushed its input buffer anyway.
- KSP-SLIP was making the decision to insert the empty
- packet or not by reading the line status register of the
- UART to see if it was still transmitting. Unfortunately,
- reading the this register also resets it, and thus screwed
- up the interrupt driven serial communications routines.
- The new code checks the output queue instead of the UART;
- this seems to virtually eliminate several problems that
-
-
-
-
-
-
- WHAT'S NEW IN KSP SLIP
-
-
- have been reported, such as a suspiciously high number of
- bad slip packets, corrupted remote IP addresses, and
- stalled transfers.
-
- New Feature: All of our software is now available via
- anonymous ftp at "scizzl.scu.edu", directory "ksp".
- Please note that there is no "e" at the end of "scizzl".
-
- 2.1: Enhancement: Now sends out a dummy IP packet at startup to
- correctly record the IP address of the BBS node in
- KSP-DVMX (in case it is being used). See discussion in
- WHATSNEW.DOC of KSP-DVMX, version 1.1.
-
- Cleanup: Replaced "Returning to PCBoard..." message with
- the more universal "Returning to BBS...".
-
- 2.0: Bug Fix: Would crash at startup if no packet driver was
- found. Corrected.
-
- Enhancement: Added the ability to override Waterloo
- TCP/IP's automatic search for the packet vector interrupt
- by using an environment variable, as in:
-
- set ksp-pv=<number>
-
- where "<number>" may be in decimal (e.g., "96"), in hex
- preceded by "0x" (e.g., "0x60"), or in octal preceded by
- "0" (e.g., "0140").
-
- Enhancement: Added information in the documentation about
- a packet driver shim for Novell with a Token-Ring_SNAP
- network.
-
- Enhancement: Performance problem when running under
- DESQview with PKTMUX solved by creation of KSP-DVMX packet
- multiplexer. Available as file KSPMUX*.ZIP, where "*" is
- the version number.
-
- Cleanup: Edited documentation to remind user to make *.MSG
- display files read-only to avoid file sharing conflicts in
- a multi-node system.
-
- 1.9: New Feature: Now DESQview "aware" to provide better
- performance in a multitasking environment. (NOTE: Two KSP
- SLIP doors running simultaneously on one machine will
- experience severe performance degradation due to problems
- in PKTMUX; we're working on a replacement for this
- package.)

-
- WHAT'S NEW IN KSP SLIP
-
-
- New Feature: Added configuration option
- "ksp-slip.local_bell" which can be set to "disabled" to
- silence the bell on the BBS console.
-
- New Feature: Added configuration option
- "ksp-slip.local_screen" which can be set to "disabled" to
- improve screen painting speed for the caller. (Does not
- affect status displays.)
-
- Enhancement: Added more information to local BBS console
- status display, including user name, location, total time
- remaining, idle time remaining, and IP address of remote
- connection.
-
- Enhancement: Added a sample script file for Trumpet
- Winsock that dials the BBS, logs in, runs the SLIP door,
- and grabs the IP address from the screen when STARTUP.MSG
- is displayed. This solves the caller's problem of not
- knowing which node (and thus which IP address) he will get
- when calling in through a rotary.
-
- 1.8: CleanUp: Discovered that only the newest versions of the
- Novell packet driver shim (ODIPKT) allow command line
- parameters to be specified in hex; older versions require
- that they be specified only in decimal. Our docs
- describing how to install ODIPKT have now been modified to
- show decimal parameters since they will work in all
- versions of ODIPKT.
-
- CleanUp: Moved the copyright notice so that it appears
- before the startup message rather than after it.
-
- 1.7: CleanUp: Whoops! The bug fix introduced in version 1.6 to
- correct the status display bug was unfortunately an
- incomplete fix. If the "ksp-slip.status" configuration
- parameter was not used at all, the screen would still be
- erased and the packet counters displayed, but without ever
- changing their values from zero. Corrected.
-
- Enhancement: Documented the "include" directive that helps
- when you have multiple nodes.
-
- CleanUp: Clarified the description of the batch file used
- to invoke the door.
-
- BugFix: If no WATTCP.CFG environment variable was used,
- there was a chance that part of memory might be
- corrupted. Corrected.
-
-
-
-
-
-
-
- WHAT'S NEW IN KSP SLIP
-
-
- 1.6: Bug Fix: The status display packet counters were not being
- updated properly (all counts were output to the bad packet
- count field). Monochrome versus color monitor detection
- was not working. Corrected.
-
- 1.5: Enhancement: Added a "ksp-slip.reserve_mins" configuration
- parameter so that the user has some BBS time remaining
- even if time expires while in the door.
-
- 1.4: Enhancement: Fossil drivers do not support break
- detection. Added code to add that break detection when
- used with fossil driver provided WATTCP.CFG file contains
- a ksp-slip.serial_port configuration option.
-
- Bug Fix: When a user dropped carrier, KSP SLIP did not
- necessarily properly unhook the serial port interrupt
- routine. Corrected.
-
- 1.3: Bug Fix: Discovered that Fossil support was not working.
- Corrected.
-
- Enhancement: Users may now send a break signal to
- terminate the SLIP connection and return to the BBS.
-
- Enhancement: Now checks for and requires 8N1 operation.
-
- Enhancement: Added ksp-slip.countdown configuration option
- to eliminate the "press any key to begin" and nine-second
- countdown at startup.
-
- 1.2: Enhancement: Replaced local console "Whirly Gig" with a
- continuously updated count of SLIP packets. Added a
- configuration parameter "ksp-slip.stats" to select output
- method: ansi, bios, or direct.
-
- New Feature: Added configuration parameter
- "ksp-slip.serial_port". If used, it overrides serial port
- address and IRQ values implied by "COMx" in DOOR.SYS and
- is provided to support non-standard configurations that
- don't use a fossil driver.
-
- 1.1: Enhancement: Added a "Whirly Gig" on the local console to
- indicate SLIP packet activity in progress.
-
- 1.0: Initial release.
