Yet more questions/problems with Interactive UNIX

[Keith Cantrell]

  Make: Gateway 2000
  Processor: Intel 80386 with 64k cache. NO floating point co-processor.
  Mother board: Micronics 386 ASIC cache
  Processor speed: 25Mhz
  Main Memory: 4 Meg.
  Disk: 110Meg ESDI
  Disk controller: Ultrastor ultra 12(F)
  Monitor: 1024x780 VGA Tatung model CM-1498X
  Video controller: OEM-VGA-300190  (says VGA-WONDER on the card)
  Serial controller: DIO-500 Multi-I/O card

More questions for you Interactive Unix Guru's out there:

  1) I have been totally unsuccessful so far being able to use my second
     serial port.  I check on the card, and it is configured as COM2 but
     when I try to start a getty on it, all I get back is:

getty: cannot open "/dev/tty01" errno: 6

     When I looked up error number 6, it says:

No such device or address

     Does anybody know what would cause this?  I even booted DOS and
     'echo'ed a string out COM2: and it did show up on the terminal that I
     have connected to it, so the hardware seems to be working.  I have
     RTFM but I can't see when you tell a device driver what comm port to
     use.  I am sure I am just missing something, if someone would PLEASE
     just point me in the right direction I would greatly appreciate it.

  2) In my system I have 4 meg of memory, but when I boot up I get the
     following message:  (The numbers are correct, I am not exactly sure
     what the verbiage said) 

Real memory 3801088
Available memory 3031040

     Is it really not seeing all of the 4 meg?  Am I correct in assuming
     that the reason why all the memory is not "Available" is that the
     kernel is taking a 770048 bytes?


  3) Is there tty driver that knows not to allow you to backspace past the
     prompt.  Needless to say this is not real important, but it is real
     annoying.


Thanks in advance,

Keith Cantrell

P.S. The response to my questions so far has been extremely low, are there
     really not that many people out there with Interactive UNIX?  If you
     know the answer to one of the questions, PLEASE don't think someone
     else will answer it, because nobody is!
