In fact, it often resets when I do.
Hmmm, this doesn't sound right. Sorry but this is getting beyond my knowledge. I've never even used spd options....my file looks like this: STD_FLAGS="session_lockout ^fourport" SETSERIAL=/bin/setserial echo -n "Configuring serial ports...." ${SETSERIAL} -b /dev/ttyS0 uart 16550A port 0x3F8 irq 4 ${STD_FLAGS} ${SETSERIAL} -b /dev/ttyS1 uart 16550A port 0x2F8 irq 3 ${STD_FLAGS} ${SETSERIAL} -bg /dev/ttyS* In ppp.options_out I just set a rate of 115200 and everything seems to work fine with my modem. I assumed all you would have to do is change the rate in this file to 230400. Anybody know whats going on here? I'm certainly interested because I intend to be getting a byte runner 16650 card and ISDN TA in a about a week. ---------------------------------------------------------------------------- Dave 'Kill a Cop' Cinege (aka Psychopath #3) --- Super Genius at Large The Oklahoma City Federal building bombing - Americas first response to government abuse http://www.psychosis.com/ Libertarian Party 1-800-682-1776 http://www.lp.org/ -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
