I am by no means a serial port amateur, but this has me stumped:
I am testing out an old system to be used as my 'net gateway (nat).
Redhat 6.0 on a k6-200, 14.4k/16450 UART at 0x3f8/IRQ4 (I'll put a 56k on it
when I get this to work.)
Kernel comes up, dmesg says that ttyS00 was found at 0x3f8/int 4.
setserial -a /dev/ttyS0 acknowledges that.
(Sidebar: why does the kernel say ttyS00 when MAKDEV won't allow for a
device named ttyS00 ?)
cat /proc/interrupt shows me that IRQ4 was taken by a serial port.
minicom (config'd with /dev/ttyS0) as device doesn't seem to communicate
with the modem. It's not an echo problem, I can't get it to off/on hook,
dial, exit command mode, etc. Nothing is happening. I've tried 2 different
I was going to try a 56k out of another box, but I don't feel like that can
be the problem. All I can think of is that I am missing something, but
nothing in the FAQ's ro HOWTO's are offering any hints...
Anyone have ideas?
