Dear List -
I have an Avery Berkel POS [Point Of Sale] scale which I wish to integrate into a POS system. The
output is sent to a RS232 port. I do not know how to extract the data.
Here is what I have about the RS232 port:
ethan@meow:~$ dmesg | grep tty
[0.00] console [tty0] enabled

Hello,
i created a bash-script to send something to serial port
(/dev/ttyACM0) and read the result.
Here my code:
- ---
DEV=/dev/ttyACM0
stty raw -F $DEV ispeed 38400 ospeed 38400 cread -cstopb -echo
echo "@00P0?" > $DEV

This is also useful for overlaying this text with a CCTV camera connected

l for the serial ports of
both machines. 'dmesg | grep serial' should tell you that the kernel has
recognized both serial ports and neither is disabled in BIOS.
Physically a serial port is comprised of a transmitter and a receiver,
either can have a blown gate and be non functiona

Hi,
Please I just need a small program which write a character ( or
several) then read it from that serial port.
I used a null modem ( since I have just on serial port device).
I want a simple serial connection. I consulted Howto on tdlp and other
, nothing is simple for me, ?? I can write on

Hum... check if it is listed:
dmesg | grep -i tty
And then review gphoto's FAQ:

Use statserial(8) to monitor the serial port state in real time.
Try connecting and discon
Hi,
How I can know if the serial port is active, gphoto2 doent find my camera
(OLYMPUS C-2000Z), this camera is supported by ghphoto2.
Thanks you.

hello,
Ok this question is about another linux distro, but I think is general for
all of them. How can I get this line when I make "dmesg | grep tty" :
console [tty0] enabled
I need to get enable the serial port...someone knows what i hav eto
do...compile kernel, type some command...
thanks
After some further study, it looks like the PCMCIA port
may actually register as two devices with only one available for
use. At least there is only one DB9 on the front of the adaptor.
From syslog:

This does seem like what I need but I haven't gotten it
to make one bit of difference yet. With the PCMCIA card out, no
/dev/ttyS0 or /dev/ttyS1 devices are present. That modem which I
believe to be a Winmodem, is probably /dev/tty

The laptop in question has a built-in dialup modem which
doesn't even show up as a serial port in Linux. In the P.C.'s
setup screen, it doesn't show up there so I can't remove or move
it out of the way, but a PCMCIA card installed containing a real
truly RS-232 port
