I am trying to find a way to continuously transfer files over a serial port. Thanks to Eric and Jonathon yesterday I learened how to send and receive files through a serial port. Many thanks. However, due to my inability to interpolate variables at the bash command line I decided to try:
my ($yr, $mo, $day, $hr, $min, $sec) = (localtime)[5,4,3,2,1,0];
my $date = $sec . $min . $hr . $day . ($mo + 1) . ($yr + 1900);
system("cat /dev/ttyS0 > $date");
This does not work well because none of the files are written until the program is killed and then they seem to be empty on the receiving end. Would it be better to make this a shell script or is perl script fixable?
Thanks for any help.
