PostPosted: Sun 08 Jan 2012, 08:30    Post subject: inconsistency  

yesterday connected puppy 4.3.1 with upgrade 4.3.1.1
but today things are gloomy.
somehow ttyusb3 is attached which starts module cdc_acm and other 3 modules.
got to lot of modprobe -r cdc_acm and other 3 modules.
sometimes pupdial shows no carriesr detect.
needs lot of reboot to overcome .
basic learned usbserial is good for it while cdc_acm is bad. option can't be loaded as it backfire by starting cdc_acm. this is quite inconsistent.reboot lot. replug lot. found device cd rom lot.
though i hope once again modprobe -v usbserial will be successful to attached to ttyusb0.

clearly it will better to change distro to slacko 5.2

ln -s /dev/ttyusb0 /dev/modem #created symlink
blacklist in bootmanager module cdc_acm.
still wvdialconf find ATDT ttyusb0 115kb with `!~!#$~$!@!~~@~!$ this type of letters. and modem is becoming harder to use in puppy 4.3.1.1
why?
port recognizing problems ?
why option or usbserial is not so clear cut about port ttyusb0 or ttyusb3 or other port specific problems?
why wvdial gives disdrain or something like that message?

Here could be ports.
Usb modem port -ttyUsb0
DM service port -ttyusb1
voice device port -ttyusb2
command control port -ttyusb3

this cantenna is better, yes? rotate it directionally for best results
153 still seems slow so I'm puzzled at the optimum, but maybe this is an ISP transmit limit, with high contention, with many shared users?

for other problems, which may be driver related, please refer to rerwin, thanks

also see barry's thread, here [rerwin is 3g developer]
