|    COM Port in Use    |

      Well Maybe I can explain a bit but who knows?                      RW> Hi all!               RW> Well, it looks like I got OS/2 Warp 4 installed in a VM and the BBS        RW> working with SIO 1.60d and VMODEM. Unfortunately, whenever I go to        RW> start the BBS, I am getting the popup saying that the virtual com port        RW> is in use when it really isn't. If I ignore through the error boxes,        RW> the BBS starts up just find and runs normally.               RW> Unfortunately, this popup is an annoyance when trying to run a front        RW> end mailer (ViaMail in this case) and it goes to load the BBS and the        RW> BBS exits back out to the mailer when a caller logs off.               RW> --- ViaMAIL!/WC v2.00        RW> * Origin: ViaMAIL! - Lightning Fast Mailer for Wildcat! (1:261/20)              I think few people have much knowledge of how OS/2 handles actual IRQ numbers       and ring level work that are really needed for carrying OS/2 back to way       before even DOS operations for some things. For example, 'normal' IRQ top       level stuff only applies to IRQ 'numbers' up to what I think I recall are       number 8. That's not enough to work with some things that we need for IRQ       level numbers which go up even way beyond number 8 especially when OS/2 is       'later' dealing with multiple CPU operations that, as I think I recall this,       are up to as many as sixteen separate CPU's which then must be able to be       coordinated with each other as to what each CPU is doing that must be       absolutely understood by any action even down to COMM ports so that things       don't violate the order of operation for multiple CPU stuff that grew up long       after the original ring level and machine language code which I was originally       working with LONG before there was OS/2 even there.              OK, If, for example, as I do even today in many operations, use Warp 4 and MP4       later in the same computer for multiple COMM port stuff that does include BBS       operations, as well as my custom ham and commercial radio total operating       stuff that controls even the antenna direction and so on as well as integrated       BBS operations, I still use SIO very well. However,when I also totally log       even telephone line use in REAL TIME to all of this with special total digital       phone line trace work even to CNID track operations in sync with radio station       control, total real time double entry bookkeeping and even GPS location for       everywhere your fingertips are touching a body in medical work, I notice       this, By the way, all this is in my over 1,000,000 lines of source code work       that still goes down to ring level and machine language stuff even today!              When I boot the system, I obviously have to use SIO to set up VMWARE for both       BBS and even total telephone line real-time logging for all of this. When I       FIRST TURN ON the special phone line monitoring for every thing a phone       company does on the line for digital use to trace where it went, I notice that       the actual FIRST IRQ port which is tracked is port 184 if my memory is       correct. That's when SIO is first set up going to the special digital       tracking device that I'm sure none of you folks ever use. Well then on any       NEXT access to the 'normal' COMM port, say number 3 or 4 that the special       little unit is listening to every phone line in the whole place for every       touch to any number or computer generated snoop on any line in real-time, the       actual port that is used is NOT 184, is say, port number 176. And that can       VERY confuse ANYTHING down to even pure CPU or multiple CPU computer unit       operations. Which, to my knowledge, ONLY OS/2 or down to even memory block       operations can ever do and Windows has NEVER been able to do after Billy Boy       stole HeathDOS from them and took Gordon Letwin away to bridge the lost of       what is now Windows from IBM.              I have NO WAY of tracing this to what you folks are complaining about here but       suspect this sort of thing is exactly what may be causing this. Worse,unless       you can get the actual people that are now using whatever to run everyting in       what they all think is their neat hidden snoop for everything that is touched       down to evey CPM in NSA or whatever country, you will, I suspect never be able       to find it unless you can totally snoop them as well in a never to be able to       decrypt trick.              Mike Luther as N117C at 1:117/100                     ---        * Origin: BV HUB CLL(979)696-3600 (1:117/100)    |
