Hi every body. I'm testing my multiport serial board (2 extra serial port)
with shared interrupt using the program found at
http://www.rts.uni-hannover.de/rtaddon/rt_serial_uprog.tar.bz2 .
I insert the module xeno_16550A.ko in the follow way:
insmod /.../xeno_16550A.ko ioaddr=0x3f8, 0x2f8, 0xd800, 0xdc00 irq=4,3,5,5
start_index=0
When I use only a extra port the program works, but when I try to write in
the first extra port and to read in the second extraport I got an error
opening the second extraport.
For example if I write in ttS0 and I read from ttyS2 all work; if I write
in ttS2 and I read from ttyS3 i get :
can't open rtser3 (the rt_dev_open return a negative file descriptor).
Thank in advance
Marco
