Kernel 2.4.18-27.8.0
FTDI_SIO version: stock
statserial version: 1.1-30 (redhat rpm)
statserial /dev/ttyUSB0 just hangs but minicom seems to
work.
This has been observed on two different computers, one
a desktop
and one a laptop.
I am guessing this is due to some unsupported ioctls.
statserial has a number of uses. One is identifying
which port is which. short pins 7 & 8 (9 pin) together
or connect/disconnect a device which asserts CTS. I
have four FTDI based byterunner serial adapters so you
can see why this can be just as important as figuring
out which port on the serial port on your motherboard
is which. Even more so, because which USB port is
which can easily change.
On my laptop,
echo "hello, world" >/dev/ttyUSB0
also produced an error, I think it was the "write
request of 0 bytes",
but I think it sent the characters ok.
