Hi all,
I develop a program that's running on two TS-7300 board. It uses TCP/IP
communication, DIO, and serial communication on the boards, and should be act
as an level-alarm program of an fuel tank. It's my first project using this
board, and I'm not too familiar with debian too..
I have to use three COM ports of the board where COM1 (ttyAM0) and COM2
(ttyAM1) works fine, but I can't use any COM port of the FPGA part of the board
(COM3-COM6 - ttyT8S0-ttyT8S3).
For test I have tried to send a simple 'a' with the echo command and check the
data with a terminal program (Docklight) at the other side (115200,None,8,1):
If I try it on COM3:
:dev# echo a > ttyT8S0
than I get in Docklight only:
<NUL><NUL><NUL><NUL><NUL><NUL><NUL><NUL><NUL>
If I try it on COM1:
:dev# echo a > ttyAM0
the answer is OK, it's what I waiting for:
a<CR><LF>
I've already tried all settings (BAUD, parity, Data bits, etc.) in Docklicht to
check, if COM3 possibly uses other setting by default, but nothing worked for
me (I don't realy know, how to ckeck/change this under Linux..).
Unfortunatelly I couldn't find any exisiting answers anywhere that could help
me, so I'd be very grateful, if anybody could give me some tip that could solve
my problem.
I'm pretty bitter, because I should have complete this project in one week, and
I can't step over this problem without any help, so its fairly urgent.
Thank you for any answer in advance!
Best regards,
Zoltan
