Hi, |

I got some strange problems while trying to setup a EXSYS EX44092 |
| 4 |
PCIe to RS232 adapter card. |
| 5 |
|
| 6 |
What I did: |
| 7 |
Start minicom, setup the serial parameters (115200 8N1) as described |
| 8 |
in the manual for the embedded system I want to connect to and reset |
| 9 |
the embedded board. |
| 10 |
|
| 11 |
Minicom prints a sequence of "."'s on the screen - thats it. I know |
| 12 |
that this embedded board is working, though. |
| 13 |
|
| 14 |
Next -- while minicom was running -- I used setserial to get the |
| 15 |
current settings of the serial interface. The baudrate was spd_normal |
| 16 |
despite the fact I had instructed minicom to set it to spd_vhi |
| 17 |
(115200 baud). Since setserial does not say anything about |
| 18 |
8N1/7N2/... parities I couldnt check this. |
| 19 |
|
| 20 |
At last I straced minicom but I didn't found anything suspicious... |
| 21 |
|
| 22 |
EXSYS claims, that this card would work under Linux (supported by |
| 23 |
drivers which are already part of the kernel sources... |
| 24 |
|
| 25 |
What did I wrong here? Why does this setup now work? |
| 26 |
|

Thank you very much for any help in advance! |
