[hcflinux] REBOOT PROBLEM

Thu Jul 18 14:43:58 EDT 2002

ok, sorry about that, your original message was unclear. 

what I said about not using setserial still stands though. Even though we access the modem through a /dev/tty char device it doesn't look anything like a serial port to the system. So setserial can't do anything with the hcfmodem.

As for the seg fault. You should send the dump output along with any relevant information and entries in the system logs to marc at mbsi.ca. 

Thirdly, there have been previous reports of /dev/ttySHCF0 disappearing after a reeboot. Browse the mailing list archives and see if any of the work arounds help you.
