[hylafax-users] LT Win Modem Config Help

[Kevin Hilton <kev_hilton@xxxxxxxxxxx>]

Ok, I know Ive been warned about using LT Win Modems with Agere chipset with hylafax, but others have stated they have gotten it to work.  I am a total newbie at configuring the modem.  The default addmodem script seems to not produce the correct results. 

I have been able to use the efax product, and have had no problem getting this to work (sending/receiving faxes).  My initialization settings for the modem using efax are the following:

# The following specifies the initialising `AT' commands for the modem
# when in fax mode.  Specify as many of these as are needed, separated
# by spaces for commands to be separated, without a prepended `AT'.
# If none is specified, the program will default to `Z &FE&D2S7=120
# &C0 M1L0', which will be correct for practically all modems

INIT: Z &FX3E&D2S7=120 &C0 M1L0

I dont know how to translate these commands to produce an appropriate /etc/hylafax/config.tty file.
The current modem portion of the file is:
ModemType:        Class1        # use this to supply a hint
Class1Cmd:        AT+FCLASS=1    # command to enter class 1
Class1PPMWaitCmd:    AT+FTS=7    # command to stop and wait before PPM
Class1TCFWaitCmd:    AT+FTS=7    # command to stop and wait before TCF
Class1EOPWaitCmd:    AT+FTS=9    # command to stop and wait before EOP
Class1SwitchingCmd:    AT+FRS=7    # silence between HDLC recv and trans
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

Thanks for help!

Currently using hylafax version 4.3.1 on ubuntu feisy 7.04 on dell laptop 5000e with modem "LT V.92 Data+Fax Modem Version 8.30". This has the agere mars chipset.  I installed martian drivers in order to make it work in Ubuntu.

Using probemodem I received the following:

robing for best speed to talk to modem: 38400 OK.

This looks like a Class 1 modem.

ATI0    RESULT = "OK"   RESPONSE = "LT V.92 Data+Fax Modem Version 8.30"
ATI1    RESULT = "OK"   RESPONSE = "E851"
ATI2    RESULT = "OK"   RESPONSE = "OK"
ATI3    RESULT = "OK"   RESPONSE = "LT V.92 Data+Fax Modem Version 8.30"
ATI4    RESULT = "OK"   RESPONSE = "72"
ATI5    RESULT = "OK"   RESPONSE = "8.30,0,19,11C1,0448,1668,2000"
ATI6    RESULT = "OK"   RESPONSE = "OK"
ATI7    RESULT = "OK"   RESPONSE = "OK"
ATI8    RESULT = "OK"   RESPONSE = "OK"
ATI9    RESULT = "OK"   RESPONSE = "North America"

Class 1 stuff...

AT+FCLASS=?     RESULT = "OK"   RESPONSE = "0,1"
AT+FCLASS?      RESULT = "OK"   RESPONSE = "1"
AT+FCLASS=0     RESULT = "OK"   RESPONSE = "OK"
AT+FCLASS=1     RESULT = "OK"   RESPONSE = "OK"
AT+FCLASS?      RESULT = "OK"   RESPONSE = "1"
AT+FJUNK=?      RESULT = "ERROR"        RESPONSE = "ERROR"
AT+FJUNK?       RESULT = "ERROR"        RESPONSE = "ERROR"
AT+FAA=?        RESULT = "OK"   RESPONSE = "0,1"
AT+FAA? RESULT = "OK"   RESPONSE = "0"
AT+FAE=?        RESULT = "ERROR"        RESPONSE = "ERROR"
AT+FAE? RESULT = "ERROR"        RESPONSE = "ERROR"
AT+FTH=?        RESULT = "OK"   RESPONSE = "3,24,48,72,73,74,96,97,98,121,122,145,146"
AT+FRH=?        RESULT = "OK"   RESPONSE = "3,24,48,72,73,74,96,97,98,121,122,145,146"
AT+FTM=?        RESULT = "OK"   RESPONSE = "3,24,48,72,73,74,96,97,98,121,122,145,146"
AT+FRM=?        RESULT = "OK"   RESPONSE = "3,24,48,72,73,74,96,97,98,121,122,145,146"
AT+FTS=?        RESULT = "ERROR"        RESPONSE = "ERROR"
AT+FRS=?        RESULT = "ERROR"        RESPONSE = "ERROR"


It appears by the output I am unable to send AT+FTS and AT+FRS commands.

This is problematic because the addmodem script returns the following:

Class1PPMWaitCmd:    AT+FTS=7    # command to stop and wait before PPM
Class1TCFWaitCmd:    AT+FTS=7    # command to stop and wait before TCF
Class1EOPWaitCmd:    AT+FTS=9    # command to stop and wait before EOP
Class1SwitchingCmd:    AT+FRS=7    # silence between HDLC recv and trans

When sending a fax with the above config I would receive:
Stop and wait failure (modem on hook)

Based on another post (the only one I could find, I changed the above to:

#Class1PPMWaitCmd:       "<delay\0727>"  # \072 == : to avoid awk problem
#Class1TCFWaitCmd:       "<delay\0727>"
#Class1EOPWaitCmd:       "<delay\0729>"
#Class1SwitchingCmd:     "<delay\0727>"  # assumption: +FRS not supported

Still however I would receive the following (unable to send a fax - Just a sample of the log file):

What else should I try or is sending faxes for me just totally out of the question.
