My pre-upgrade 8525 showed as an HTC Modem in Control Panel / Phone and Modem Options / Modems tab before upgrade. Now it doesn't. It's that darn Internet Sharing app, which actually works great and gave 725 kbps here near DC one morning on 3G. Wow. That's fast.
You see, it appears Cingular removed WModem.exe and the help and shortcut files from the upgrade. I tried WModem.exe from my SX66 and it ran but it did not show up as a modem. That's probably because of registry or the hardware port for the modem differs from SX66 (Blue Angel) to 8525 (Hermes).
Do any of you pre-upgrade 8525 owners have WModem.exe at minimum from your My Device/Windows directory? Can you share it here? (It's an invisible system file on a Winows PC. Turn on Tools / Folder Options / View / Show system files to see it and transfer it)
If you can do this, I will try a wireless fax on Cingular with the 8525. I did send wireless faxes on Cingular with my SX66, but they each cut off at the same page position, about 1/5 down. Cingular credited months of CSD when I explained that fault.
Yes, wireless faxing is possible. As stated above, your account must be provisioned with CSD from Cingular for $3.99 / month. I have had that since way back in 2005 or 2004 and Cingular confirms they will not market CSD to new accounts or provision CSD to existing accounts; you have to be grandfathered in, and even then support is nearly nonexistent.
I work with a volunteer group and fax PIHI under HIPPA regs to the front desk during meetings. That's my fax use; it's tethered.
P.S. 2007-11-18: Cingular 3rd tier tech support has ironed out most problems with CSD as I continue to learn about wireless faxing. I found a Cingular ROM of early release on the web but it won't load, most likely because the 6.0 Professional ROM has a 2+ bootloader, but we (our Cingular Family) have one upgrade avaialble, so I'll get an 8925, which an HTC rep promised has got the Wmodem app, saying "I've got one here in my hand, and it's there". The BT modem doesn't fax. I am exploring ETSI modem standards and learning my extended AT codes like AT+GMM, etc. I used the Motorola RAZR belonging to my Cingular Family primary account holder to send a complete wireless fax the other day, so I know CSD is working. I'm working to set up intenet connection sharing on my home PC by dialing home but that's not free, like it is with a T-mobile My Faves account. Slow and steady progress like the CSD service itself. A call from Cingular 3rd tier to me is scheduled for [email protected]
EST to finalize this service. I"ll ask for a year's credit of CSD because the rep admitted the account was misprovisioned.
