Other Help Topics :: serial port problem

Hi,

i want to connect 2 seriel devices.
A Touchterminal which works fine and a Chip-reader.

The system recieves data from the touchpanel on every serial port i connect it to, but i got only data from the chip reader, when i connect it to the port, on which the touchpaneldriver listens.
I got the data with "od </dev/ttyS*".
All irqs and ports are set properly. I checked it with setserial.
Windows recieves data from the reader on every serial port.

Has anyone a idea?
Thanks a lot.

What kind of chip-reader?

Can we get some specs for the machine?

More info is needed to figure out what's up.

Oh sorry,

its a little board with a via processor, 667Mhz, 128Mb Ram

Chip Reader maybe the wrong word. It is selfmade.
It reads a number from a transponder that you hold near the reader and sends it to the serial port.

But i solved the problem this morning. The od command is not reliable in this case. The data was transmitted correctly. The problem was that my program could not load a library. The library was in the directory of the program, but it must be in a global directory like /usr/lib.

Many greetings,
