Hello:
I want to be able to use a laptop as a serial console from time to time. My
current laptop does not have a RS232 serial port, so, I found a PCMCIA card
with a serial port.
It appears to be recognized fine by the OS on boot (dmesg below). However,
when I try to use minicom on that line (/dev/cua03), it does not work. I
cannot establish a connection to the "server" from the minicom console.
Also, even though minicom appears to come up ok, when I try to exit from
minicom, I get the "reseting" message, the screen clears, but then the
terminal window hangs. I can see that the minicom process is still up. I
can kill it (pkill -9 minicom), and then I get a prompt back in the terminal
window that was previously frozen.
If I try to shutdown with the "hung" minicom process, shutdown eventually
gives me "some processes would not die; ps axl advised." This would seem to
indicate I have a problem with the crappy pcmcia card.
Also, if I use a usb serial adapter I have (which is in use elsewhere - and
change /dev/cua03 to /dev/ttyU0 in minicom), minicom works.
So, is there anything I can do, or is this a hardware problem? How can I
find out for sure?
Thanks for any advice.
Ted
