[hylafax-users] Nokia 7110 & Siemens S35i versus HylaFAX

["Hugo Mayer" <hugo.mayer@gmx.net>]

Hi people,

as I could get a lot of helpful pieces of information relating to my
configuration of HylaFAX on my Linux box I would like to thank all the guys that
posted their experiences to this mailing list so far. My HylaFAX setup works
perfectly with Elsa Microlink 33 TQV modem on Linux 2.2.14 (Suse 6.4), both
"send" & "receive" do the work wonderfully. Additionally I could test HylaFAX
with 2 mobile phones having data&fax modems built-in: Siemens S35i and Nokia
7110. Here are my results (for those of course who are interested in):

ENVIRONMENT:
a) Linux 2.2.14 Kernel (self-compiled) coming with Suse 6.4 distribution
b) serial devices: /dev/ttyS0 (Elsa Microlink 33 TQV for send/recv) and
/dev/ttyS1 (Siemens S35i | Nokia 7110 for send-only)
c) both mobile phones connected via serial cable with the port (-> DLR-3 for
Nokia 7110)
c) HylaFAX 4.1beta2 (without patches)


SIEMENS S35i
----------------------
This mobile phone works fine as Class 1 modem without any modifications
necessary for default configuration file /var/spool/fax/etc/config. Here are
important, active options:
---------------------
ModemType:                Class1          # use this to supply a hint
ModemRate:                19200           # rate for DCE-DTE communication
ModemFlowControl:    xonxoff         # XON/XOFF flow control assumed

Class1Cmd:              AT+FCLASS=1     # command to enter class 1
Class1TCFResponseDelay: 75              # 75ms delay between recv TCF & response
Class1SendPPMDelay:     75              # 75ms delay before sending PPM
Class1SendTCFDelay:     75              # 75ms delay between sending DCS & TCF
Class1TrainingRecovery: 1500            # 1.5sec delay after training failure
Class1RecvAbortOK:      200             # wait 200ms for abort response
Class1FrameOverhead:    4               # 4 byte overhead in recvd HDLC frames
Class1RecvIdentTimer:   40000           # 35+5secs waiting for ident frames
Class1TCFMaxNonZero:    10              # max 10% of data may be non-zero
Class1TCFMinRun:        1000            # min run is 2/3rds of TCF duration
-----------------------
I could make a very fine experience with XON/XOFF flow control method, also
sending/receiving SMS messages. I would recommend it as default flow control for
this device.


NOKIA 7110
-----------------
This mobile phone caused more problems relating to the configuration. First, it
returns class string "0,1,1.0,2,2.0" to the "capable classes" request, it causes
the script "/usr/sbin/faxaddmodem" to recognize it as Class 1 modem only. This
seems to be buggy, as there is no "case" entry in the mentioned script for such
a situation:

    1,2,2.0)            configureClass1and2and2dot0Modem;;
    0,1,2,2.0)          configureClass1and2and2dot0Modem;;
    0,1,2,2.0,*)        configureClass1and2and2dot0Modem;;
    0,1,1.0,2,2.0)      configureClass1and2and2dot0Modem;; # <-- this entry
added by myself
    0,1,1.0,2,2.0,*)    configureClass1and2and2dot0Modem;;

After inserting this entry the "faxaddmodem" script offers now all classes for
selection. I decided to take Class 2.0 as setup base. The second problem I had
to deal with was "low performance" of Nokia 7110, it responses very slowly to AT
commands (also to AT-based SMS commands). I had the typical MODEM timeout
already after first initialization attempt, so I increased delay between 2 AT
commands to 100 ms. I noticed also that the modem does not work with XON/XOFF at
all, here RTS/CTS was necessary. I activated also the lines:
ModemVerboseResultsCmd: ATV1            # enable verbose command results
ModemResultCodesCmd:    ATQ0            # enable result codes
this helped to avoid TIMEOUTS also (do not ask me why). The registration of
modem in send-only environment should be done using following statement:
/usr/sbin/faxmodem  -c  '(0-1),(0-3),(0-4),(0-2),(0-3),(0-1),(0-1),(0-7)'  ttyS1
This sequence of chars can be obtained by command "AT+FCC=?" using minicom or
cu.
Here are important, active options from /var/spool/fax/etc/config.ttyS1:
