Hallo everyone, I have problem with communication over serial port.
This is what I am having problem with:
I need to make communication with device which has usb on rs232 convertor and fifo memory.
PC sent data to fifo memory in same time device read data from fifo memory.
When micro (in device) sees that memory is full, it change state of CTS signal. CTS signal stays in that state until memory is half full.
I have problem to write code in C that sends data to device but considering CTS.
I send data as byte array, memory is 4K , speed is 38400
Does anyone have a clue how I can solve this mistery

Its the LPC2129 ARM7TDMI on board 100x125 and
You really don't need to do anything except enabling hardware flow control in your UART (I think your chip has an least one UART that has a modem interface). Check your user manual.
