Having dealt with the RS232 protocol for many years I am wondering why you are suddenly so vexed about it. The protocol precedes computing devices, having been created as a communication protocol for teleprinters (originally the 5 bit code before becoming the 7 bit and 8 bit codes we have today). Auto-negotiation takes intelligence at each end. As that was not available at that time we just accepted the need to get things set-up right before we started. > Please be inspired to release open and free RFC-definitions now, so that > "vintage" serial communication will work smoothly - and with backward > compatibility and of cause with auto "null-modem" functionality. > > I am looking forward to, that all out-of-bound signals can automatically > be mapped by software by a series of signal pertubations and response > measurements. I am sure there is an official way to propose a new RFC if you need to. You could try and do that if you have some ideas that you would like to see implemented as standard. I am not sure you would get much support with such an old protocol though. -- ******************************************************************** Paul E.
