We have a little program, made in dos (works under all windows systems), that our customers use for purchasing goods. We are having difficulty with the LTwinmodem that IBM has in their newer Aptiva machines. Our com module will not work with that modem at all. I want to either program my self out of it or get a communikation tool that our program can use to connect with the modem.
Does anyone know of a communcation program that can be called from my dos program to communicate via modem? It can be commercial, we wil pay for using the program offcourse.

I have an LTWinmodem and I know the problem your having. You have a wide array Com ports and IRQ's that this thing can use. Have you tried disabling Com 1 and Com 2 in BIOS and see if you can force the modems Com Port and IRQ? Normally the IBM pc's have PS/2 mouse and keyboard so you should be able to do this if you don't have anything else using them. If that doesn't work, try going to WWW.NONAGS.COM and you'll probably find some freeware or shareware there that will help you with your problem.

Good Luck!

Just a comment:
Although I'm unfamiliar with the LTWinmodem, I can tell you that other "Winmodems" will not work in Dos.
They're designed to be operated in the Windows enviornment, and not recognized by Dos programs at all.

Ralph

Time to move up!
They could get a different modem, but if you can get your customers to upgrade to a Windows program, that problem will be solved. (Along with others in the future)
Let me know if you need more.

Ralph

Let me say that we allready have considered moving our purcase system to windows. The problem has, up till now been, that a lot of our cuatumers still had 386'es and that meant they could not run win95 in a sufficient speed. That was the main reason, for us to do the whole thing in dos.

Thank you all for the help, at least now I know why i cant get that modem to react, I thought I was going crazy..*grinning*

Tomas

Tomas,
If you click on my name, and look at the bottom of the page, you will see that yours is the only "D" grade awarded to me in the last ten questions I have answered.
If the answer did not help you, I would have preferred that you reject it by re-opening the question.

Okay your are right...
It is not that i dont value your opinion. Its just that the answer for me right here and now is not to make a win version of the program. I just wanted a fast solution to the modem problem i have. It seems, from newsgruops and all sort of experts that it is impossible to get the modem to react to a dos program. That is why i graded your answer to a D, because you told me to get my customers to upgrade, well im coporgrammer on this and a we are allready slowly but surely working on the winversion. This modemtype hit the market not so long ago and our customers are some of the slowest in the world to upgrade their equipment. Dentists!!
It was not for putting you down i graded it to a D, but because the suggestion about making a winversion allready occured to us.

Yours Truly

Tomas

Is the solution to your problem any less correct because I proposed it?
I don't think the fact that my proposed answer had already occurred to you was ever mentioned.
Therefore, without that information, I proposed what I (and apparently, you) consider to be the best solution to your problem.
As I said, I'd rather you had rejected my answer (commenting why) than to receive a poor grade for an answer which is correct.
Regards,
Ralph
