- Information about this document
- ===============================
-
- This document was written as an introduction to InterCom for OS/2 by Jonathan
- Tew. It is based on copies of E-mail messages that Jonathan provided to me,
- experience using the program during the beta testing phase and beyond, and
- discussions with Jonathan. It is not intended to be an end-all be-all list
- of technical support for InterCom, but rather a short introduction to the
- program and source for solutions to some of the more common problems users
- experience. While I have tried to ensure that the information in this
- document is accurate and timely, sometimes things get missed, so if your
- puter blows up, don't blame me, Jonathan or this document. =:-)

- Where do I get InterCom?
- ========================
-
- (a) The latest release can be found on Hobbes in the /incoming
- directory or /os2/network/tcpip directory. The file name will be
- "icxxx.zip", where "xxx" is the version number. You can also find the
- package on revsoft2.is.net in the /ic directory.
-
- Note: The archive on Hobbes will eventually be moved to the
- /os2/network/tcpip directory.
-

- Commonly asked Questions and Answers
- ====================================
-
- [a]
-
- Q: Why can't the other person hear me after I have connected to them
- and said something?
- Q: Once I have called and connected to the other person I say something,
- but they can't hear me. Why is this happening?
-
- A: These things should be done to insure proper setup.
-
- 1) Is the microphone plugged into the correct port on the sound
- card. To test this record your answering machine message and
- then choose review and see if you hear yourself. If you hear
- yourself than your side is configured correctly.
- 2) Do both people have the master audio level (configured through
- multimedia folder) and the InterCom audio level (configured
- from volume under the InterCom menu) set to or near 100.
-
- [b]
-
- Q: Is InterCom compatible with other internet telephones?
-
- A: InterCom is a native OS/2 32-Bit Application. It was designed
- from the ground up to run specifically on OS/2 and is not based
- off any other previously written products. This allows you to
- take the greatest advantage of OS/2. The power of an OS/2 based
- product can not be contained in a single threaded application. This
- means that versions for Windows, Macintosh, and other single
- threaded operating systems is impossible. Another reason that
- compatibility can not be achieved is the lack of specifications
- available on internet telephones. These products are evolving at
- a rapid pace so a set standard at this time would simply limit the
- functionality of the products and their ability to change with new
- technology. Maybe as time passes the products will evolve to a
- point where a good standard could be published, but this isn't the
- time. There might also be plans to port InterCom to other platforms
- once the OS/2 version reaches a final stage.
-
- [c.1]
-
- Q: Why is there only one ICTalk server to log in to?
- Q: Is revsoft2.is.net the only available ICTalk server for InterCom?
-
- A: At the time of this writing yes it is the only one. The InterCom
- package includes the ICTalk server executable free of charge. If
- you have a static IP address and/or hostname and wish to run an
- ICTalk server to serve other InterCom users feel free to do so.
- If you inform us of it's existance we can include it in next
- release of InterCom and we can also update our web pages informing
- users of it's presence.
-
- [c.2]
-
- Q: What is this ICTALK.EXE file?
- Q: Do I need the ictalk.exe file for it to work?
-
- A: The ICTALK.EXE file is only needed if you want to run your own
- ICTalk server. You don't need anything except INTERCOM.EXE to run
- the product. So if you aren't going to run an ICTalk server then you
- can safely delete that file and save a bit of HD space.
-
- [d]
-
- Q: When will InterCom move up to full-duplex?
- Q: One question I have is when you will be supporting asyncronous
- mode, where both people can speak at the same time. This is
- now a standard feature in the Windows-based products. I'm hoping
- you will be adding it soon.
-
- A: One of the problem is the lack of full duplex sound cards for the
- OS/2 environment. Either the sound card or the drivers for it make
- most audio devices half duplex. I urge you to pressure the makers
- of your sound card to create full duplex drivers if the hardware
- is full duplex, but the drivers currently aren't. Support for
- full duplex will be added in the future.
-
- [e]
-
- Q: Why does my Thinkpad have problems with InterCom?
- Q: I am running a thinkpad 755c3 with 24megs of ram. My CPU is a 486DX.
- I am using OS2 Wrap. The thinkpad uses Mwave and I have installed
- the 2.00 drivers. When I try and record with the answering machine
- message I get an error in Module INTERCOM.CPP, error is unsupported
- sampling rate action unknown. Any help you can offer?
-
- A: Some sound cards including the one in the IBM ThinkPad can't support
- sampling rates like 8000. Adjust the sampling rate to 11025 and you
- should have no problem. The answer to this question also applies to
- other sound cards that have the unsupported sampling rate problem.
-
- [f]
-
- Q: My soundcard is 100% compatible, why won't it work?
- Q: I have a (Brand X) 16-bit Soundcard, it says it is 100% SoundBlaster
- compatible, but your program tells me it is in 8-bit mode. Why
- can't it figure out what my card is?
-
- A: InterCom reports whatever MMPM says your card is, so if your OS/2
- system tells InterCom that your card is 8-bit, that's what InterCom
- sees it as. Another thing to check is what sound blaster drivers
- OS/2 is using to run your compatible card. If the driver is the
- one for the SB Pro than it is running your card in 8-bit mode even
- though it might be a 16 bit card. You should have the Sound Blaster
- 16 drivers installed in order to run the card in 16-bit mode. One
- way to check to see if you are using 8 bit drivers with your 16 bit
- card is to see it sbpro.sys is found in your config.sys
-
- [g]
-
- Q: Everyone I talk with says my voice sounds really strange on
- their end, I can still talk with them though.
-
- A: You have probably selected a sample rate that is too low. It
- tends to make your voice sound as if it is a 78 RPM record being
- played at 33 RPM. Simply raising your sample rate should fix it.
-
- [h]
- Q: Does talking via the ICTalk server slow the connection down?
- Q: Does it take alot of system resources to run an ICTalk server?
-
- A: The ICTalk server simply maintains a list of people who are
- currently running InterCom. Since the amount of data transmitted
- to maintain this list is very minute it doesn't take a very
- powerful system to run the server software. If you connect
- to someone by clicking their name from one of the ICTalk server
- lists then the connection is no slow. The connection between
- you and the person you are talking to is direct. No data passes
- through the server.
-
- [i]
- Q: What limitations will I encounter if I'm behind a firewall?
-
- A: The firewalls that are commonly found in large companies such
- as IBM will prevent TCP/IP from receiving connections. This
- means that you will not be able to receive calls. A way of
- circumventing this is being looked in to, but nothing for
- sure has been decided. If two people are behind different
- firewalls then connection between them will be impossible
- at this time. Another solution to this problem is to setup
- your own ICTalk server behind the firewall. The server
- software is ICTALK.EXE and it is located in the InterCom
- directory. By running a server it will provide everyone
- behind the firewall a place to connect to.
-
- [j]
- Q: What is the Connectix QuickCam and how does it work with
- InterCom.
-
- A: The Connectix QuickCam is a black and white video capture
- device that attaches to the printer port. The camera
- retails for about $99 at the local computer stores. For
- more information on purchasing the QuickCam visit the
- Connectix WWW page at http://www.connectix.com
- The QuickCam is very easy to use and setup. There is
- no hardware cards to install in the computer or drivers
- to install in OS/2.

- Future Features.
- ================
-
- Well many features are being planned and/or considered. But until they
- actually get implemented, tested and released it wouldn't be prudent to
- talk about them here.
-
- [7]
- Features Wish-list.
- ===================
- See [6]. If you have ideas for future improvements please feel free to
- send them to us. We are always willing to listen to the wants of our users.
