Re: [ts-7000] TSDIO Driver 1.0 Byte Write Problem

["Rich Wilson" <>]

0x0A looks a lot like a line feed (\n) to me.
Does echo -n work?

Hello,

I have successfully installed the tsdio device driver that is posted
on the files section of this web site. I am currently using a TS-7250
running the 2.4.26-ts11 kernel.

All of the single bit read and write command are working correctly and
I can control individual LEDs tied to the ports. My current problem is
that writes to the bytewide device /dev/tsdio/twriteall returns a 0x0A
to the DIO port. Any ascii charters sent using echo...

echo 0 > /dev/tsdio/twriteall DIO output = 0x0A
echo 255 > /dev/tsdio/twriteall DIO output = 0x0A

produce the same results.

I can still controll all of the pins on the port with the...

echo 1 > /dev/tsdia/twrite0
echo 0 > /dev/tsdia/twrite0

I have also tried making my own device...

mknod /dev/leds c 238 153

but get the exact same results.

There are no examples of how to read or write the full 8bit device in
the readme file.

What am I doing wrong when writing to the full 8bits of the character
device?
