- Recent changes to G8BPQ switching system
-
-
- Version 4.05
-
-
- Internal TNC2 application support removed (except in Data Engine). A new
- driver, BPQHTNC2.COM replaces it.
-
- Parameter added to DEDHOST to suppress PacketCluster 'Autotimer' messages.
-
- Stations heard list included (MHEARD command).
-
- REJ handling changed to try to stop multiple repeat transmissions.
-
- Parameter added to disable the *** LINKED function. This is required for
- some gateway systems, but can be abused. I suggest it is disabled
- unless required by a gateway application.
-
- Facility added to route transmitted frames to a different port. This is
- for a 'Single transmitter, Multiple receivers' environment. If parameter
- TXPORT=n is added to a port, all frames for that port will be sent on port n.
-
- Support added for hardware interrupts 8-15.
-
- Support added for Baycom USCC-Karte. Ports A and B are the 1200 baud ports.
- Port C is the TTL port, and port D the G3RUH compatible 9600 baud port.
-
- The documention on the various external application drivers has been merged
- into file DRIVERS.DOC.
-
- SOFTDCD should now work on HDLC cards.
-
-
-
- Version 4.05e July 92
-
- DEDHOST driver now prevents multiple incomming connects (For PacketCluster)
-
- DCD Interrupt handling speeded up to improve SOFTDCD.
-
- New Non-TSR version for operation as Network node only (See SWITCH.DOC).
-
- Feature added to allow CTEXT to be sent to all users.
-
- Various Bux fixes to BPQHTNC2.
-
-
- Version 4.06 September 92
-
-
- I am working (unfortunately rather slowly) on rationalising all the .DOC
- files into a coherent SYSOP's Manual. In this release, the descriptions
- of all the programs (except interface drivers) have been combined into
- PROGS.DOC, and files BPQCODE.DOC and CONFIG.DOC merged. Other files have
- been brought up to date.
-
-
- Several bugs fixed in BPQHTNC2. New Function (AH=1F/AL=3) added to set
- PACLEN to recommended value from node.
-
- All numeric alises were treated as port numbers.
-
- Reflected routes now get OBSCOUNT set, so they dont vanish too soon.
-
- ON-OFF keying for CWID (mainly for use with G3RUH type modems, and
- radios with a fast keying characteristic (eg Kantronics DataRadios)).
-
- Code added to stop sessions sticking in Disconnecting state.
-
- '*** LINKED to' processing fixed on Data Engine version.
-
- Clocking setup on port C of BAYCOM USCC card (the TTL port) changed to
- be compatible with the BAYCOM modem.
-
- The driver code for linking to a NET/ROM diode matrix as been fixed. I had
- misunderstood the system, and used the wrong polarity of signals. So inverters
- were required to connect the PC to the matrix. Now a simple 5 wire cable with
- one pull-up resistor can be used to link a diode matrix port intended for a
- TNC2 to the PC. Remember that to operate with a matrix, you must set FULLDUP=0
- in BPQCFG.TXT. This time I have tested it pretty throughly!
-
- PC 2 --------------------- 3 MATRIX Port
- 3 --------------------- 2 (Wired for TNC2)
- 4 --------------------- 5
- -- 5 --------------------- 20
- |
- R 7 --------------------- 7
- |
- -- 20 R = 10K resistor
-
-
- One side-affect is that it is no longer possible to use the NETROM
- port with a Half-Duplex landline modem. If anyone is actually using
- such as system, please let me know, and I'll restore the facility.
-
-
- Version 4.06a October 1992
-
- Fix a bug introduced in 4.06 that disables the lost interrupt detection
- code. This could result in an ASYNC port hanging, and the switch running
- out of buffers. Only BPQCODE.EXE and SWITCH.EXE are changed from the
- 4.06 version.
-
- Also the sample BPQCFG.TXT included a KISS port with IOADDR=3F8h, IRQ=3
- which is invalid. This has been fixed.
-
-
- Version 4.06b
-
- Experimental version - not released.
-
-
- Version 4.06c December 92
-
- Incudes code to support my IP Router program IPGATE.EXE. Currently IPGATE
- runs as a forground program, so will normally require the use of DesqView.
- See file IPGATE.DOC for further information.
-
-
- Version 4.06d
-
- This was an experiment in use of Selective Reject (SREJ) processing. This is
- designed to improve throughput, particularly when runing with a large MAXFRAME,
- by retransmitting only missing frames, rather than everything following a
- dropped frame. However it is not working correctly yet, so has been disabled.
-
-
- Version 4.06e March 93
-
- This fixes a problem where a lost tx interrupt on an HDLC hard could cause
- the port to lock up, and the switch eventually run out of buffers.
-
-
- Version 4.06f April 93
-
- Fixes a bug in 4.06e which prevented access to the node via a digipeater.
-
- Adds a driver to allow two or more BPQ nodes to be linked via Ethernet (see
- section on ODIDRV in DRIVERS.DOC)
-
-
- Version 4.06g May 93
-
- Changed processing of RR(F) and REJ(F) received in response to an I(P)
- frame. Any missing frames are now retransmitted immediately, instead of
- waiting until after the next RR(P) command.
-
- Added extra options to the STATS display, mainly for uses with more than 7
- radio ports. S S displays just the system and L3/L4 counters. S n displays L2
- counts for up to 7 ports, starting with port n.
-
-
- Version 4.06k September 93
-
- Versions h-j were either controlled or beta release only.
-
- A bit more tinkering with REJ processing.
-
- Improvements to IPGATE (see IPGATE.DOC), and integration of IPGATE
- into SWITCH.EXE.
-
- Fixed bug which could cause a corrupt 'NODES' broadcast to crash the switch.
-
- Fixed PACLEN processing on ports using BPQHTNC2. Paclen should now be set
- to the value recommended by the switch, which in the case of level 2 connects
- will be the PORT PACLEN.
-
- Fixed problem which prevented BPQNODES and BPQDUMP finding the switch if
- there were no comms ports using interrupts 2-7.
-
- Driver for PA0HZP's OptoSCC card is now documented. This driver has actually
- been present for several versions, but I could never get it to work. It now
- appears that my card is faulty, as others have used the driver successfully.
-
-
- Version 4.07 December 93
-
- Fixed problem with REJ handling, which could cause lots of repeats of a
- frame, particularly on a very busy link.
-
- Added new parameter, MINQUAL, to PORTS configuration. This defines the
- lowest quality node that will be included in a Nodes broadcast on the
- port.
-
- Added new parameter LEARN Y/N to IPGATE.CFG. This allows the automatic
- route learning mechanism to be disabled.
-
- Version 4.07a January 1994
-
- Added timestamps to monitor display in PAC4 and SWITCH.
-
- Added REBOOT command to SYSOPH - causes PC to reboot.
-
-
- See file QEMMPROB for a description of a problem which can arise when using
- QEMM7. Many thanks to Mike, N1BEE for bringing this to my attention.
-
-
- Version 4.08beta June 1994
-
- Fixes problem with JNOS BPQHOST interface.
-
- Fixes problem that could cause links to hang up when using IPGATE.
-
- Includes Windows DLL and VxD to allow use of BPQ Host mode from Windows
- applications. See WINBPQ.DOC for details.
-
-
- Version 4.08 October 1994
-
- Provides a means of creating aliases for connect commands. (ie a Node could
- have a command BBS, which is converted internally to C GB7XXX)
-
- Includes additional BPQHOST API functions to simplify managing stream
- numbers.
-
-
- Version 4.08a January 1995
-
- Internal processing speeded up. Should make a noticable improvement in
- throughput on TSR version, when running fast links.
-
- IPGATE now generates ICMP TTL exceeded messages.
-
- Error in IPGATE UDP checksum routine fixed
-
- Test OS/2 version included
