I'm using STREAMS to do ARQ data transfer over a full duplex serial line, so after I write to the line I have to check for an ACK. But how do I know that my output buffer has cleared through my UART before I try to read? Isn't there a danger that I will read back in some of the data I'm trying to send when I try to read the ACK? If so, is there a way to handle this without writing a new device driver? --tj leone@ohsu3b2.ohsu.edu
