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.
