I hope I'm doing something wrong, however stupid. I even sent a modem back to U.S. Robotics for "repair." The output of stty -a -f /dev/ttyd0 shows it (I'm not sure if it's the rate at which it is connecting to the computer or the line) as: speed 9600 baud; 0 rows; 0 columns; lflags: -icanon -isig -iexten -echo -echoe -echok -echoke -echonl -echoctl -echoprt -altwerase -noflsh -tostop -flusho -pendin -nokerninfo -extproc iflags: -istrip -icrnl -inlcr -igncr -ixon -ixoff -ixany -imaxbel -ignbrk -brkint -inpck -ignpar -parmrk oflags: -opost -onlcr -oxtabs cflags: cread cs8 -parenb -parodd hupcl -clocal -cstopb -crtscts -dsrflow -dtrflow -mdmbuf cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>; eol2 = <undef>; erase = ^?; intr = ^C; kill = ^U; lnext = ^V; min = 1; quit = ^\; reprint = ^R; start = ^Q; status = ^T; stop = ^S; susp = ^Z; time = 0; werase = ^W; Annelise To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
