Mark,

I could use some help with the Zoom Modem.

1. ECS.EXE Ver 4.0.025
2. Pentium MMX, 233 mhz
3. Phone interface-C and Phone-Call TYPE
4. Zoom ComStar SVD Model 2800

I actually have two questions/problems:

Problem 1.

5. Error Message...  "Error: Call Aborted No Carrier Detected"
6. "Set" Phone-Call TYPE to call a number where continuous Ringback will be
   detected. (The line is not busy and the call will not be answered).

   Comment: 50 seconds (12-15 rings) is needed for the call to terminate. "No
                   Carrier Detected" is not listed as a valid state.

Problem 2.

5. Error Message...  No error message.
6. "Set" Phone-Call TYPE to call a cellular number.

    Comment: "Call Completed" is indicated even though Ringback can still be
                    heard. (No one has answered).

Since the Zoom 2800 is no longer listed as a recommended modem do I need to 
upgrade to the ComStar 56K?

If I append an "S" register command ('S7=25") to the ATDT Command Line I was 
not successful in reducing the "No Carrier Detected" timeout. Do you limit  
VALID AT Commands to only those listed in the documentation?

Thanks

Larry C.
