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. -J.P. Posted by Termi1980 on Jan. 07 2005,08:20
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.
