Greetings,

I am trying to write a string size of 0x7FFF to COM1 using RTS and CTS. The
following sequence does not do the trick since I have set some variables
within struct DCB to activate RTS and CTS usage.  Does anyone know this
trick?  

idComDev = OpenComm("COM1", 1024U, 0x7FFFU);
BuildCommDCB("COM1:9600,n,8,1", &dcb); 
dcb.CtsTimeout = 10;
dcb.fRtsDisable = 0;
WriteComm(idComDev, p, 0x7FFFU); 

By the way, OpenComm() has UINT for the transmission queue size but only works
up to 0x7FFF!  

Thank you.  

Scott
