I’m trying to read in from the Serial Port using dev_read () function, i
sent some string to the Serial Port through
HyperTerminal in my window NT machine. From the help, it says that three
argument min, time, timeout when they are
all 0s, this function returns immidiately… but i find it blocking unless i
make the proxy argument 1, what’s wrong??
Also, dev_read() only can get soemthing when I press ‘enter’ key on the
HyperTerminal, how can i
get the string without the carriage return?
