I'm using AT&T SimulTask 386 version 2.0 (which is actually VP/ix 1.something) on an AT&T SVR3.2.1 system. I'm having a problem with MS-Kermit 3.1 When I run Kermit, with Simultask set up to allow access to the COM2 port, I get the error message: ?Warning: no harware for this serial port ?This port will be operated through the Bios as BIOS2 In other words, Kermit has decided it will communicate with COM2 using only standard Bios calls. The problem is, when I go into terminal mode, the screen just starts filling with the character "2". The program doesn't crash - I can exit terminal mode and mess with the comm parameters, etc. It's as if Kermit thinks it's receiving a steady stream of "2"'s from the COM port. I've tried resetting Kermit to use the hardware ports, but it just gives the above error message again. Does anyone have any ideas? I also use Telix 3.12, and have had no problems at all, but I prefer MS-Kermit as it has superior terminal emulation and a better implementation of the Kermit protocol.

I have a similar problem running MS-Kermit 3.1 under MS-DOS. My modem is on COM4. When I tell Kermit to use COM4, it tells me there is no hardware for this port, and uses BIOS4. When I connect, I get a screen full of characters. I'm not sure, but I think Kermit's port definitions are screwed up. After a lot of trial and error, I found that I can get Kermit to work by telling it to use COM2. *All* of my other programs use COM4. Very strange. Anyway, you might try using COM4. Good luck...

But I can't remember the details! Well, the real problem is VI/IX is not revealing the serial ports as (pseudo) hardware items. The difference between what MS-DOS Kermit does about it and what some other comms programs do is fairly simple to deduce: MSK checks out the port before doing anything to change it or to put it into service. Goodness knows what the system has at the address indicated in segment 40h of the Bios, but we'd better not do real damage if it's not a standard serial port. Anyway, that's been my view and hence that's what the Kermit code does. Somewhere in my dusty mental archives I recall that the VP/IX docs comment upon making the serial ports available. You might want to review the fine print in those documents. Btw, I tried a test installation of VP/IX, the version you mention, on my SVR4 system and it's no-go. Thus if you upgrade Unix then assume that VP/IX will need an upgrade too. Joe Doupnik

Very > strange. Anyway, you might try using COM4. > > Good luck... > > Dennis ------------------------------- Aw, come on fellas. By now everyone knows that there is no definition for COM3 and COM4. MS-DOS Kermit has the good sense to look before leaping, more than can be said for some comms programs. If you want COM4 with Kermit then you can do one of two things. With MSK v3.10 you can give Kermit commands SET COM4 \x0nnn irq where nnn is the hex port, irq is irq or SET COM3 ditto Or you can put the port address of COMx in the segment 40h work area where everything rational looks for it. The four words (two bytes) starting at 40:0h are the port addresses for COM1..4. Kermit looks there, the Bios looks there. The POST part of the Bios is responsible for filling in the numbers but IBM (hence everyone else) looks for only the first two ports; you can add to the system's knowledge. Joe D.
