regarding libmodbus-0.0.1

The latest version of libmodbus is 1.2.4 and I never released the 0.0.1 one.
I never tested libmodbus with RS-485 because I don't have the hardware, there is certainly available documentation on the subject on the Web...

Anyone has tried?

Ooops, the latest is 2.0.2!

Akbar, You are getting your source from one of the release links on
https://launchpad.net/libmodbus
right?

No, but considering http://en.wikipedia.org/wiki/EIA-485 claims it to be a serial bus, then as long as the 485 equipment in use presents itself to the OS's user space as a serial interface, it should work as any other serial link with libmodbus. I am not sure if the user space serial controls might limit the coms to 115kbps vs the 35Mbps wikipedia lists as max for 485.

Thanks for your help!!
I downloaded the latest version now from https://launchpad.net/libmodbus that is 2.0.2
now i want to test the hardware to make sure that it is reading from my hardware..it was wondering is there any example programs that i can test in RTU mode over serial communication(RS485).
i see a unit-test-msater.c iam not sure that i can use to test my hardware for serial .

Thanks
!!

i was wondering as iam testing in RTU mode .do i have to uncomment thefunction modbus_init_rtu and comment the modbus_init_tcp in example programs
random-test-master.c
unit-test-master.c

i just have one address 0*04,i was wondering about ADDRESS_START and ADDRESS_END

i was wondering where i have to give the read function address(0*03)

Iam sorry if i ask too many qestions at one time

Thanks

after intalling iam trying to run the example program random-test-slave.c
but it gives me the error pkg-confiq command not found
at the time of insallation when i run ./configure it displays something like

i was wondering is this could be the problem

Thanks

To compile a program you need to install the required development environment (gcc, devel lib and so on)!
