Hi,
Note: the text below will be seen better if copied to notepad or any fixed-width font
viewer...
Here comes a part of my code: (I 've cut some checks...)
============================
void SerCommand(char *str) {
SerSend(refNum,str, StrLen(str),&err);
}
Boolean SerReply(char *buf) {
UInt32 number=0;
UInt16 i;
for (i=0;i<BUF_SIZE;i++)
buf[i] = 0;
err = SerReceiveWait(refNum,1,SysTicksPerSecond()*1); // wait for any reply
if (err) {
SerClearErr(refNum);
FrmCustomAlert(ConfirmAlert,"Failed to read","\nTimeout.","\n1char");
return false;
}
err = SerReceiveWait(refNum,BUF_SIZE-1-32,SysTicksPerSecond()/2); // some time more
// I can set larger tiem. *** IT DOESNOT AFFECT *** the problem.
if (err == serErrLineErr) {
SerClearErr(refNum);
FrmCustomAlert(ConfirmAlert,"Failed to read","\nErrInLine.","\nnot 1char");
return false;
}
err = SerReceiveCheck(refNum,&number);
if (err == serErrLineErr) {
SerClearErr(refNum);
FrmCustomAlert(ConfirmAlert,"Failed to read","\nErrInLine.","\nCount buffer");
return false;
}
if (SerReceive(refNum,buf,number,-1,&err)!=number) {
if (err == serErrLineErr)
SerClearErr(refNum);
SerReceiveFlush(refNum,-1);
FrmCustomAlert(ConfirmAlert,"Failed to read","\nLost in buffer.","\nCount
buffer");
return false;
}
return true;
}
===================================
Now the problem:
I have tried to send a set of commands via IrDA to cellular phones (Siemens S25 and
Ericsson SH888)
and it works fine except for one specific command (+CSCA) sent to Ericsson only. The
command is
<at+csca?> and Palm does not receive the whole phone reply. Just a part of it. I have
to sent e.g.
<AT> command to get lost part of previous reply.
So the dump log for Ericsson SH888 (mystique splitting) and Siemens S25 (works fine)
is below.
Record starting with -> means sent to phone, starting with <- means phone reply. I do
sent 3
commands:
1. AT+CGMI
2. AT+CSCA?
3. AT
to both phones.

=========================
So the final question: How one could explain this strange behaviour of Ericsson with
CSCA command?
It works fine with other commands. And I can get lost part of second reply even if a
do close
infrared port of Palm by hand before sending the last command. So it looks like some
mistique of
SerReceiveCheck function....
