Perhaps, this question is not directly related to linux kernel,
however ,this list
has always generated helpful hints. so I'll appreciate any help
Or I'd be equally happy with a pointer to a site with more info.
So here's the problem I am facing:
I try to connect my router and a PC running almighty Linux through
console
port (router ) and serial port (Linux). Now where the confusion takes a
hold
of me is the determining the correct serial port. In /proc/interrupts I
get
the following: 4: 4 + serial. That makes me think of IRQ 4 = COM 1 or
COM 3 in Linux nomenclature cua0 or cua2 (Am I right here?).
I am using kermit to access cua0 -> router.
The cabling is correct , because I was able access the same type of
router (in reserve) with different PC using the same cable.
My question would be : What is the correct port if not cua* ?
Any particular tricky issue as far as kermit is concerned ?
What's the difference between cua* and ttyS* (except major
5 vs 4) ?
If that above is confusing or incomplete please feel free to drop
me a mail, so I could clarify .
Thank for everybody's precious time
Sincerely
