Flow control is a bit tricky when it comes to sending things to the modem. I found that our "standard procedure" with cu etc. sometimes hangs as well. And things actually get worse if I break this down into basic operations. That may take a bit to figure out. Meanwhile, the best work-around seems to be to just try a number of times. - Werner _______________________________________________ devel mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/devel
