Running stty -a dialed in from Hyperterminal I get the results below. min is set to 1. The only differences from what you sent in your reply are echoe, echoctl, and echoke without '-'.
Does it matter what the TERM environment variable is set to? I have configured agetty to set it to vt100 and to nothing (defualt to cygwin). I get the same results. The problem is not just with the end of line \r. As I type characters, every second character causes the echo of the two characters. If the end of line happens to be the second of a pair, the command works. $ stty -a speed 38400 baud; rows 24; columns 80; line = 0; intr = ^C; quit = ^\; erase = ^H; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0; -parenb -parodd cs8 -hupcl -cstopb cread -clocal -crtscts -ignbrk brkint -ignpar -parmrk -inpck istrip -inlcr -igncr icrnl ixon -ixoff -iuclc ixany imaxbel opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 isig icanon iexten echo echoe -echok -echonl -noflsh -tostop echoctl echoke "Randall R Schulz" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > BB, > > Well, it's a long shot, but System V Unix-style tty drivers, including > the Cygwin emulation on Windows, have a parameter, "min," that tells > the minimum number of characters that must be present in the input > buffer before it will be activated.
