Mario,
I just loaded it 6 times in a row without a single error... How? I'm
scared but I have to say it... I tried to load the program in Windows
95. There must be something in NT that is preventing to load big
programs.
I tried to check the serial status before running nqc with command
MODE COM2:
Status for device COM2:
-----------------------
Baud: 1200
Parity: Even
Data Bits: 7
Stop Bits: 1
Timeout: OFF
XON/XOFF: OFF
CTS handshaking: OFF
DSR handshaking: OFF
DSR sensitivity: OFF
DTR circuit: ON
RTS circuit: ON
and after:
Status for device COM2:
-----------------------
Baud: 2400
Parity: Odd
Data Bits: 8
Stop Bits: 1
Timeout: OFF
XON/XOFF: OFF
CTS handshaking: OFF
DSR handshaking: OFF
DSR sensitivity: OFF
DTR circuit: ON
RTS circuit: OFF
Here is the firmdl.c code where it opens and uses the serial without a
glitch:
ios.c_cflag = CREAD | CLOCAL | CS8 | PARENB | PARODD;
cfsetispeed(&ios, B2400);
cfsetospeed(&ios, B2400);
tcsetattr(fd, TCSANOW, &ios);
And here is the code in NQC:
dcb.BaudRate = speed;
dcb.fBinary = 1;
dcb.fOutxCtsFlow = 0;
dcb.fOutxDsrFlow = 0;
dcb.fDtrControl = DTR_CONTROL_ENABLE; // DTR flow control
type
dcb.fDsrSensitivity = 0; // DSR sensitivity
dcb.fTXContinueOnXoff = 0; // XOFF continues Tx
dcb.fOutX = 0; // XON/XOFF out flow control
dcb.fInX = 0; // XON/XOFF in flow control
dcb.fErrorChar = 0; // enable error replacement
dcb.fNull = 0; // enable null stripping
dcb.fRtsControl = 0; // RTS flow control
dcb.fAbortOnError = 1; // abort reads/writes on error
dcb.XonLim = 100;
dcb.XoffLim = 100;
dcb.ByteSize = 8 - (opts & kPSerial_DataMask);
dcb.Parity = (opts & kPSerial_ParityMask) >> kPSerial_ParityShift;
dcb.StopBits = ((opts & kPSerial_StopMask) >> kPSerial_StopShift);
// 0,1,2
dcb.XonChar = 1;
dcb.XoffChar = 2;
dcb.ErrorChar = 0;
dcb.EofChar = 0;
dcb.EvtChar = 0;
return SetCommState(fFile, &dcb);
What do you think? Wouldn't it be better to have some command line
parameter to overload the previous behaviour?
Ciao.
Marco.
