| ksanny Tl Posts: 7 | Posted - 1/22/2002 6:47:09 PM    I have a 3CP5610A modem that answers all incoming calls. I have been asked to type in the command ATS0=0 from hyper-terminal to disable the answering feature. The problem I have is that my motherboard does not allow me to set my ports and IRQ's easily. I have a Soyo Dragon+ motherboard that allows devices to share IRQ's and such. My modem works fine on IRQ 11 on COM3. It shares the IRQ with the onboard LAN, video card and onboard sound device. I am lead to believe that this is normal with this board, based on all the messages I see in the various message boards. I have disabled COM1 and COM2 on the motherboard. When I try to have hyper-terminal connect to COM3, I get a message " Unable to open COM3. Please check your port settings". Is there another way to input the S0=0 command to the modem, other than thru hyper-terminal? OS: Windows 2000 Server Thanks. |
| Bob Starnes Tl Posts: 4360 USA | Posted - 1/22/2002 8:33:30 PM Are you sure that the modem is on Com3? Quite often the USR modems install to Com5. Can you connect to the internet ok? Can you access the modem in the Control Panel, Modems, Diagnostics? Make sure that no other applications are using the modem, for instance, you can't be on the internet and use Hyperterminal at the same time. Might click Ctrl-Alt-Del and check to see if RNAAPP is running, if so the 'End Task' on it and try Hyperterminal again. Any voice messaging software loaded at startup or running in the background? What software did you have loaded that set the modem to auto-answer? |

| ksanny Tl Posts: 7 | Posted - 1/23/2002 6:01:01 AM Yes, my modem is using COM3. I have no problems with my modem connecting to the internet. And the modem is accessible thru Control Panel, Modems, Diagnostics. Putting the string in the extra settings will not help my situation, I am told.. it needs to be written to the modem somehow. There are no other processes or programs running... I've gone into the services panel and killed every service the server will allow too... Any more ideas? |

| charles Tl Posts: 5879 USA | Posted - 1/23/2002 9:14:07 AM S0=0 is set by default when the modem is installed so it was change by some 3rd party software.You might reinstall the modem and then check the modem setting in hyperterminal. Are still unable to access hyperterminal? |
| v.Richard Tl Posts: 6222 USA | Posted - 1/23/2002 9:47:20 AM  There may be software running that you don't know about - and also preventing you from opening the modem's COM port with Hyperterminal. (Like maybe USR's Control Center, or other USR modem control applet). In other words, it is doubtful you have any type of configuration/IRQ/COMPort problem related to the modem - you simply have something running that you don't want running, or you have the settings for it incorrect for your situation. Aloha! Richard. |

| Bob Starnes Tl Posts: 4360 USA | Posted - 1/23/2002 9:14:03 PM Tried using Hyperterminal with the modem name and entering your own phone number for the number to be dialed? Then after you get the BUSY message you should be able to 'talk' to the modem and issue at&f1s0=0&w That should reset the s0 register to zero, auto-answer off. Or you could use the above string in the Extra Settings, connect to your ISP, disconnect and remove the string from the Extra Settings (once the s0=0 is written with the '&w' the string is no longer needed).

| ksanny Tl Posts: 7 | Posted - 1/24/2002 5:45:30 PM After days of killing processes and uninstalling programs and components, I still have not been able to find the program that is locking up my COM port. Today I came across an article in the Microsoft KnowledgeBase (Q157827) that deal with RAS and modems. I canabalized some of those suggestions. I found the inf file being used by the modem and then changed the following lines as follows: HKR, Hangup, 1,, "AT&F1<cr>" --> HKR, Hangup, 1,, "AT&F1S0=0<cr>" I then re-installed the modem. The modem has stopped picking up calls. I can still connect to the internet. In short, I seemed to have solved my problem.. kind of, I think. The question is.. are the entries I have modified alright to live with, or are there issues I should be aware of by changing those entries? Thank you |
| v.Richard Tl Posts: 6222 USA | Posted - 1/24/2002 5:53:30 PM I can't think of a problem with what you've done. It's like you're telling the modem I TOLD YOU NOT TO ANSWER AND I MEAN IT....!  Aloha! Richard. |
| ksanny Tl Posts: 7 | Posted - 1/24/2002 5:57:36 PM Thank you very very much!!! I feel pretty smug!! And thank you Bob Starnes.. I didn't see your last reply before I went a-hacking. Its good to know you can do the stuff you suggested too. |
| Bob Starnes Tl Posts: 4360 USA | Posted - 1/24/2002 6:48:06 PM Only problem with your "hack" is that if you ever do want the modem to auto anwswer, it may not. |
| ksanny Tl Posts: 7 | Posted - 1/25/2002 10:09:46 AM Understood. Thanks for all your help. |
