Hi,
I'm using pmcom for serial communication between windows-pc and dos-pc
(Rocky 512) (speed 115200)
My serial ports are UART 16C550 compatible with a fifo of 16 bytes
During data transfer (XON-XOFF handshaking) a buffer overrun happens
frequently, even with a small amount of data (<16 byte)
After a overrun no transfer is possible anymore.
How can this overrun condition be resetted?
Why does this happen ? In my previous application in16bit (Greenleaf com
lib) i could master 4 comports at a speed of 115200
Are ISR in PM that slow ?

Where can i find a good serial library for djgpp (RM ISR) (a commercial one
?)

Thanks
Patrick
