Modem Not Responding

I inherited an older Packard Bell computer that I am hoping to set up for a friend to have email access.  The model is LEGEND 2000 PLUS MM and it was setup to run Dos 6.2 and Windows for Workgroups ver. 3.11.  The networks setup is set at "No Windows support for networks". The modem appears to be a 14400 baud unit but probably is not the original installed when the system was first purchased. The modem manual that came with the system says "Fax Modem 1442PC V.32bis", no other ID.

I have had trouble getting the system to use the modem.  The Windows Terminal program DOES dial out all right on the modem, so I don't think there is anything wrong with the modem. I used the terminal program to dial into my local ISP PPP/SLIP account.  But I cannot get Trumpet Winsock or AOL to dial using the modem.  Trumpet Winsock says that the modem is not responding to the initialization attempt and the AOL program says that it could not initialize the modem.  The modems jumpers are addressed at COM2.  As far as I know, all programs using the modem have their port parameters for the modem set to COM2.  But there is an anomaly on boot-up that I haven't been able to resolve: The setup utility displays a warning: "* System configuration was invalid. Review all configuration settings. * Conflict with Serial/Modem Port and/or IRQ Selection".  I can't make out what the conflict might be. The setup program shows the following for the com ports: "Serial port 2/Modem Port: [ COM2 ] [   IRQ 3 ]; Serial port 1: [ COM1 ] [  IRQ 4 ]; COM3/COM4 Base: [ 3E8/2E8 ].

I found the AOLDIAG program and ran it.  I got the following output:

I don't know what the significance of the errors shown for ATI6 and ATI7.  Thanks for your efforts in figuring this one out.

Looks like the modem and COM 2 may be at war.  Can you jumper the modem for COM 3, and assign it interrupt 5 or 7, which ever is open?

Thanks, I will try your suggestion tomorrow.  Your way may get me around the CMOS setup anamoly.  However, I seem to be having some luck without changing the setup and the jumpers.
-
Despite the CMOS setup anamoly which I mentioned in the original question, I continued to try to get Trumpet Winsock to work after submitting the question to Experts Exchange. I figured if the "Terminal" program could work, there should be no reason why I couldn't get the Trumpet Winsock program to dial using the modem.
-
I had been successful with using the windows "Terminal" program to dial out on the modem, so I lifted the modem initialization string from that program and inserted it into the "trmpwsk.ini" file in the appropriate place. The file originally had a different string.  I'm not sure whether it was really necessary to change the string.
-
The "Login.cmd" file that it (Trumpet) uses for the dial up process had the following statements:
-
              output "ATZ"$\13
              if ! [input 5 OK\n]
                  display "Modem is not responding"\n
                  abort
              end
-
These lines preceded the actual ATDT dial command.  This code evidently expects an "OK" return from the modem which it must not be getting.
I'm not familiar with what the modem should return upon receiving the "ATZ" command, but this "if" seemed to be detecting a problem that was the stumbling block.  I took a chance and commented out this part of the Login.cmd file and saved the file.  Then I reran Trumpet Winsock.  The program now was able to dial out on the modem.  I have not noticed any repercussions for having bypassed the test made by the commented out code.
-
I still haven't gotten AOL to initialize the modem though I've attempted similar modifications to its modem setup. - jdumas

ATZ is a reset command.  typically it resets the modem to factory defaults, but try using  AT&F instead ("reset to factory defaults") instead and see if you have better luck.. Make a record of your changes somewhere!

Expert99:
I have not been able to use your suggestion to jumper the modem to COM3 and assigne interrupt 5 or 7.  The CMOS setup program does not allow the assignment of those interrupts to COM3.  The program only allows the assignment of interrupts 3 or 4.  For other systems your suggestion my be a viable solution.   I think I've gone about as far as I'm going to go on this computer.  I have gotten a workable work around which gives my friend access to the internet and e-mail on this machine.  Thanks for your efforts. - jdumas
