I’m using QNX 6.4 and an Athena II(Diamond Systems). I’m trying to use the serial ports of one EMM-OPT-XT REV D(Diamond Systems).
To mount the serial ports I use the command devc-8250. ( The serial ports appear on the “dev” as ser1, ser2, ser3…).
The problem is that the use of it is limited, one byte is sent each 50 ms, it’s too slow.
The serial ports of the Athena II works normally, but the ports of the Emerald don’t.
I use the command stty >dev/ser1 to test the serial ports.
There’s any other configuration that has to be set?
