Smartlink modem driver doesn't send "RING" messages.
Hello,
This is new behavior in the new Lenny installation. Under Etch it worked
fine. I have restored the same configuration files that worked before,
but now the modem never answers. The following init-chat line used to work
before:
init-chat "" AT+FCLASS=8 OK ATN1S0=0S13=1 OK
The S0 register is defined as "rings to auto answer". If I'm not mistaken
vgetty takes control of the modem and generates an "A" command when it's
time to answer, after the number of rings specified in voice.conf.
S13=1 is echo commands. I have also tried X0 and X1 in the init-chat
line, per the file smartlink_v92_12312001.pdf as found via google.
These are all the S registers that ati4 return:
ati4
s00=000 s01=000 s02=043 s03=013 s04=010 s05=008 s06=002 s07=060
s08=002 s09=006 s10=007 s11=100 s12=050 s13=001 s14=000 s15=001
s16=001 s17=000 s18=000 s19=000 s20=000 s21=000 s22=000 s23=000
OK
And this is what the above file says they mean:
s00=000 Rings to auto-answer rings default=0
s01=000 Ring counter rings default=0
s02=043 Escape character ASCII default=43
s03=013 CR character ASCII default=13
s04=010 LF character ASCII default=10
s05=008 BS character ASCII default=8
s06=002 Wait time for dial tone seconds default=8
s07=060 Wait time for carrier seconds default=60
s08=002 Pause time for dial seconds default=2
s09=006 Carrier detect resp. t 0.1 s default=6
s10=007 Carrier loss disc. t 0.1 s default=7
s11=100 DTMF Tone Duration 0.001s default=100
s12=050 Reserved
s13=001 Echo 0-1 default=1
s14=000 Quiet 0-1 default=0
s15=001 Verbose 0-1 default=1
s16=001 Pulse/Tone 0-1 default=1
s17=000 Reserved
s18=000 Test timer (0-255) minutes default=0
s19=000 Sys inactivity timer minutes default=0
s20=000 Reserved
s21=000 Break Length (0-9) 100ms default=9
s22=000 Origin/answer (0-1) 0-1 default=0
s23=000 XOFF character ASCII default=19
Changing s0 and s22 (the only registers that could remotely be
applicable) changes nothing.
>From the Etch vgetty, I remember that with each ring, "RING" showed up in
the log file. Now nothing shows up. A google search found a very similar
problem, from 2004, but no solution:
http://osdir.com/ml/linux.linmodem/2004-07/msg00083.html
I have also connected to /dev/ttySL0 with kermit (that's how I got the
ati4 output above) and while calling the phone number no "RING" messages
are generated. Yes, I have tested that the incoming wire does receive
the rings by plugging a phone in it.
This is the log file. When vgetty used to work, I also had some (all?) of
these errors, but the modem answered. This is a built-in modem in a
Dell 8600: sl-modem-source 2.9.9d+e-pre2-12 and sl-modem-daemon
2.9.9d+e-pre2-12 (that come with the Lenny distribution).
Can anyone provide a hint or solution? Thanks.
