I am having trouble accessing Verizon's TAP terminal, and always get disconnected after TAP protocol is detected. I have zero trouble sending to other wireless carriers such as Alltel.

Debug logfile entries for the aborted connection are as follows....

There does appear to be "garbage" in the longer response string (3rd from end) when compared to the Alltel carrier response string, but I don't know that to be fact.

Any help you can provide will be much appreciated!

Can you also please post the setting you are using on your Carrier Settings screen for this carrier.

Gladly...current carrier settings for failing Verizon TAP below.....

TAP protocol
No Failover
18668230501

1200, 8-N-1 ( 7-e-1 failed to work on my oddball USR modem... see forum entry http://www.notepage.net/forum/viewtopic.php?t=79 )

AT&F0Q0V1X4&D2&B1&K0&M0&N2
max character = 120
no password
0 msg limit
drop unprintable characters
no pulse dial

Note that with exception of the phone #, this carrier configuration is identical to an existing and working carrier config for Alltel.

I tested the terminal from here at n,8,1 and I am able to connect. You might want to try settings the baud rate to 300 and changing the carrier init string to have a '&N1' instead of an '&N2', at the end.

Please post the log if you get different results.

It seems changing to 300 baud and &N1 has helped to a degree. Automatic TAP mode accepted it says now, but I never get a response back from the carrier after the block is sent. However, the responses are inline with the other working carrier, Alltel....well, up to the point it stops responding. :)

I have attached the logs as requested. Please let me know if I need to provide more information or if we have done all we can.

Only two options left:

1. try a higher baud rate: set it to 2400 and use &N3 in the init string

2. try a different modem (external USR are usually best)

Setting the baud rate to 2400 and using &N3 did not make a difference. Still no response from the carrier after sending the block. I will have to hunt a bit for another USR Sportster 28.8, though it will be external if I can find the modem stash. :)

Will post back after swapping modems, unless you just happen to think of something else to try in the interim.

A different USR 28.8 was used, with like results. Must I assume at this point there is nothing else to try?

Did you try the new modem at 1200 baud, and at both n,8,1 and e,7,1 ?
