Redhat 2.4.18.14 running on a 133 P1 Compaq laptop.
I am trying to access some serial data coming into the first serial
port(ttyS0?) using minicom. When I run minicom as either root or a
normal user I get the following error:
minicom: cannot open /dev/ttys0: Input/output error
The ls -l for /dev/ttys0 are as follows:
crw-rw-rw- 1 root tty 3, 48 Aug 30 2002 /dev/ttys0
I added my username to the tty group, but that didn't have any effect.
Is this caused by a lockdown by some security tool that I haven't
detected yet?
I can capture this serial data fine using Win98 on com1.
