If you find that SpecView is not making a successful modem connection then the first thing to try is to do the same action using HyperTerminal.
This was a component of Windows and therefore is an independent piece of software. However, in Windows Vista, Windows 7 and 8, HyperTerminal is not included, but it is possible to download this useful tool from various websites, the files needed are:
hypertrm.exe
hypertrm.dll
In most cases SpecView will perform the same as HyperTerminal. With HyperTerminal you can either connect to:
| • | Direct to the COM Port of the TAPI device – this allows you to use AT commands (see: www.computerhope.com/atcom.htm). |
| • | Direct to the modem – this allows you to dial a number via an easy to use interface and best emulates what SpecView will do |
Remember: If HyperTerminal cannot do it, then SpecView cannot either!
Where is HyperTerminal?
You will find HyperTerminal under:
| • | WinXP |
| o | “Start->All Programs->Accessories->Communications”. |
| • | Win98 |
| o | “Start->Programs->Accessories->Communications”. |
| o | If you do not have it installed then you will need to visit the “Control Panel->Add/Remove Programs->Windows Setup”. Check the “Communications” box. Hit the “Details” button. Ensure that “HyperTerminal” is checked. |
| • | Win95 |
| o | “Start->Programs->Accessories”. |
| o | If you do not have it installed then you will need to visit the “Control Panel->Add/Remove Programs->Windows Setup”. Check the “Communications” box. Hit the “Details” button. Ensure that “HyperTerminal” is checked. |
Using HyperTerminal to simulate SpecView Remote connecting to SpecView Local:
Firstly ensure that the modem speakers are on. This is done via Windows Control Panel. This will help considerably in understanding what's going on.
1. To check that the modem on the Remote PC is basically working and can be 'seen' on the COM port, do the following:
On the Remote PC use HyperTerminal 'Direct to the COM Port' that the modem is connected to.
Type AT (although the AT characters will not necessarily be shown on the screen) it should respond with OK which will prove that the modem can be accessed on the COM port.
Then exit HyperTerminal.
2. Check that the modem on the Local PC can be accessed:
By doing the same as above on the Local PC.
3. Then on the Local PC run HyperTerminal again but this time select the modem from the list (enter any telephone number as this won't be used)
Click [Cancel] instead of [Dial], then choose the 'Wait for call' menu command from the Call menu.
Now on the Remote PC run HyperTerminal and again select the modem from the list enter the telephone number of the modem on the Local and click [Dial] and watch the call status until it shows 'Connected'. Then characters typed will echo into the other HyperTerminal screen.
To disconnect use the 'Disconnect' tool on the toolbar.
If any of this doesn't work then contact your computer's administrator and ask them to:
- Check the modem drivers have been recognised by checking the Windows Control Panel - Modems on the PCs at both ends of the connection.
- Check the wiring connections
- Check that the number being dialled is correct
- Do the noises being heard reflect what's going on, for example is a ringing tone heard.
It is very important to ensure that these steps work correctly BEFORE attempting to use SpecView
Remember: If HyperTerminal cannot do it, then SpecView cannot either!
4. Once the above steps have been completed and are all working OK then:
Use SpecView to make the connection, first ensure HyperTerminal isn't running (because SpecView & HyperTerminal cannot run at the same time using the same COM port).
Run SpecView Local and setup the connection.
Then in the Remote PC run SpecView and click the [Remote] button.
Either click [New...] to add a new connection, or [Edit...] to edit an existing connection. Ensure the number to dial & settings are correct as described in setup. Click [Save] then [Connect].
