[hylafax-users] Failure to raise V.21 transmission carrier.

[Abhijit Hoskeri <abhijit@xxxxxxxxxxxxxx>]

Hi,

I am using HylaFax 4.2.3 on a "U.S. Robotics 56K FAX EXT Rev.
11.16.63/Configuration Profile..." modem. I have a problem receiving
faxes on this combination. I keep getting the error "Failure to raise
V.21 transmission carrier."

A sample session is given below:

My (Modem related) Hylafax config for this modem is as follows:

ModemType:              Class1          # use class 1 interface
ModemRate:              19200           # rate for DCE-DTE communication
ModemFlowControl:       xonxoff         # software flow control
ModemSetupDTRCmd:       ATS13=1&D2      # setup so DTR drop resets modem
ModemSetupDCDCmd:       AT&C1           # setup so DCD reflects carrier (or not)
ModemNoFlowCmd:         AT&H0&I0&R1     # setup modem for no flow control
ModemHardFlowCmd:       AT&H1&I0&R2     # setup modem for hardware flow control

Class1SFLOCmd:          ""              # modem does this automatically
Class1ResponseWaitCmd:  AT+FRS=1        # wait after sending TCF for response
ModemSetupAACmd:        AT+FCLASS=0     # leave modem idling in class 0
ModemAnswerCmd:         AT+FCLASS=1A    # answer in Class 1

Thanks for any clue...
Will Upgrading help in any way?
