Do you really know for sure how thse pins are internally connected? If there are any pull-up or -down resistors? And how your UART is implemented internally? And if the driver actually reads the pins? I wrote: this is what your serial driver reports. This does not necessarily mean that this is actually the state of the externally accessable pin on the serial connector... > here is my info: This looks ok. > Now we can still see the RTS/CTS/DSR/CD/DTR are still on,why? Because this is what you serial driver reports about the current state of these pins? > it my kermit version's problem? No. Ummm... why do you bother? Is anything not working?
