remote modem for meridian mail answers-can't talk to mail 1

[mindamartine]

Hello All,

I have an Opt.61 with Meridian Mail Rls. 13
My remote access modem answers but when I do a "Control R" to refresh the screen nothings happens. I have swapped out modems and the results are the same. Once in a great while it will actually work (1 out of 25 plus trys).
Any ideas? This is driving me bonkers as I have to drive 15 miles to reset a password.
Thanks in advance!

Minda

Are you going in with settings of 8N1 and using VT220 emulation?

Yes.

Actually using Hyper Terminal, it does not have a VT220 emulation. I use VT100 for all my other Meridian Mail access.

I have found it necessary in the past to follow the instruction below for modem strings - hope this helps.


U.S. Robotics Setup for Meridian Mail

The Ventel 9600 Plus modem (A0381458) supplied for Meridian Mail Remote Access and the Ventel 2400 modem (A0345963) have been replaced by the U.S. Robotics Sportster modem in the Modem kit NTDK66AA A0657330. This bulletin describes the setup procedures for the U.S. Robotics Sportster 14.4 kbps modem or the U. S. Robotics Sportster 28.8 kbps , both available in the NTDK66AA package, when used with Meridian Mail for the following features and platforms:
• Remote Access - Modular EC, Modular Option, Modular GP, Options, EC11 and Card Option
• Networking - Modular EC, Modular Option, Options, EC11, Modular GP, MSM and Card Option


The setup documented here should not be used for other purposes (e.g., for connecting to a Meridian 1 or for Meridian Mail Reporter). Please refer to appropriate NTP documentation to configure the modem for other applications.

Remote Access

The U.S. Robotics Sportster 14.4 kbps external modem (U.S. Robotics part number 0268-0) and the U.S. Robotics Sportster 28.8 kbps are now supported for Meridian Mail Remote Access on all Meridian Mail releases on the following platforms:
• Modular Option EC
• Modular Option
• Modular Option GP
• Options (NT/XT, ST/RT)

For releases prior to Meridian Mail Release 10, the modem has to be set up for use at 2400 bps operation. In Meridian Mail Release 10, the baud rate of the Meridian Mail CPU can be set at either 2400 bps or 9600 bps. Modems must be configured so the baud rate matches that of the terminal and the CPU’s NVRAM (non–volatile memory) using the Speed Change utility. The utility is available through the System Installation and Modification menu on the Install/Data tape (on the System Operation Utility menu), or in the System and Feature Dependent Utilities on the TOOLS menu. After the speed is set, the terminal and remote support modem must be reset to match the baud rate of the CPU card. Further instructions on setting the baud rate of the CPU card are contained in Meridian Mail "Installation and Maintenance Guide" NTP for the platform.

Configuration for Remote Access using the Meridian Mail administration terminal

Prior to use, the local and remote modems should be configured (the local modem is the one connected to the Meridian Mail system). This is accomplished by connecting the modem to a VT220 compatible terminal (the Meridian Mail administration terminal) and sending commands to it as described.

Note: Before configuring the modem, the terminal must first be configured to the desired speed that matches the system speed as indicated above. This determines the modem’s default speed when resetting or powering up. Other terminal settings should be as documented in the "Installation and Maintenance Guide" NTP.
— For 2400 bps modem access, set the terminal to 2400 bps.
— For 9600 bps modem access, set the terminal to 9600 bps.

Programming the modem

1 Connect one end of a straight RS232 cable (NTND91AA/AB) to the 25-pin modem connector.
2 Plug the modem power cord into an AC receptacle.
3 Power on the modem.
4 Temporarily disconnect the administration terminal from the A/B switchbox.
5 Connect the free end of the modem cable to the terminal for the purpose of configuring the modem. The terminal should be set to the speed that the Meridian Mail administration terminal will be using, either 2400 bps or 9600 bps. The modem will automatically save this speed when the configuration is saved.
6 Program the modem. Refer to the appropriate procedure below for local or remote modem.
7 Disconnect the administration terminal from the modem cable.
8 Reconnect the administration terminal to the A/B switchbox.
9 For a local modem, connect the free end of the modem cable to the B connector on the A/B switchbox.
10 For a local modem, connect the modem to the phone line provided for remote support.
DIP switch settings for the U.S. Robotics Sportster for remote access

The U.S. Robotics Sportster modem has DIP switches on the rear. These have to be set as indicated in the programming instructions. The down position is the ON position for the switch, and the switches are numbered from 1 through 8.

Local modem programming

These instructions are for the modem that is to be connected to the Meridian Mail system.

Power off the modem. Set the DIP switches 1,3,7,8 DOWN for programming; all other switches should be UP. Power on the modem. Enter the commands below from the administration terminal to configure the modem.

Enter the following command Modem response
AT&F0<Return> OK
ATS0=1 <Return> OK
AT&B1 <Return> OK
ATY0<Return> OK
ATQ1 <Return> No response is seen on the terminal after this command
AT&W0 <Return>
AT&W1 <Return>

Power the modem off. Set the DIP switches 1,4,8 DOWN; all other switches should be UP.



Remote modem programming

These instructions are for the modem that is to be used to dial in to the Meridian Mail system.

Power off the modem. Set the DIP switches 3,5,7,8 DOWN for programming; all other switches should be UP. Power on the modem. Enter the commands below from the administration terminal to configure the modem.

Enter the following command Modem response
AT&F0<Return> OK
ATS0=0 <Return> OK
AT&M0<Return> OK
ATY0<Return> OK
AT&W0 <Return> OK
AT&W1 <Return> OK

Power the modem off. Set the DIP switches 3,5,8 DOWN; all other switches should be UP.

Note: The U.S. Robotics modem may be used to dial into Meridian Mail systems utilizing other supported local modems (e.g., Ventel EC2400-33). The remote modem/terminal should only be used at 9600bps when the local modem is capable of 9600bps operation (e.g., the U.S. Robotics Sportster, but not the Ventel EC2400-33) AND the Meridian Mail local administration terminal is used at 9600bps. In all other cases, 2400bps should be used. This will prevent flow control problems that may otherwise occur.

The use of other modems (e.g., U.S. Robotics Courier) as a remote modem is possible, but the settings for those modems have to be determined by trial and error. A general guideline for use of other modems is that the remote modem speed should be selected as recommended above, and error correction should be disabled. If connection is not possible, then it is necessary to use a supported modem.

Networking

The U.S. Robotics Sportster 14.4 kbps and 28.8 kbps external modems is now supported for Meridian Mail Networking on all Meridian Mail releases on the following platforms:
• Modular Option EC
• Modular Option
• Modular Option GP
• Options (NT/XT, ST/RT)
• Card Option
• MSM (Note: The modem is configured differently when used on the MSM platform and differs for the 14.4 and 28.8 kbps modems. Confirm that the correct MSM configuration is followed.)
Configuration for Networking using the Meridian Mail administration terminal

Prior to use, modems should be configured. This is accomplished by connecting the modem to a VT220 compatible terminal (the Meridian Mail administration terminal) and sending commands to it as described.

Note: Before configuring the modem, the terminal must first be configured to 2400 bps. This determines the modem’s default speed when resetting or powering up. Other terminal settings should be as documented in the "Installation and Maintenance Guide" NTP.


Programming the modem

1 Connect one end of a straight RS232 cable (NTND91AA/AB) to the 25-pin modem connector.
2 Plug the modem power cord into an AC receptacle.
3 Power on the modem.
4 Temporarily disconnect the administration terminal from the A/B switchbox.
5 Connect the free end of the modem cable to the terminal for the purpose of configuring the modem. The terminal should be set to 2400 bps. The modem will automatically save this speed when the configuration is saved.
6 Program the modem. Refer to the appropriate procedure below for the correct platform.
7 Disconnect the administration terminal from the modem cable.
8 Reconnect the administration terminal to the A/B switchbox. Set the terminal back to the speed used for Meridian Mail administration, if altered in step 5.
9 The modem can then be connected to the Meridian Mail networking port and is ready for use. Details of this connection and telephone line setup are identical to that described in the NTPs for other networking modems.
