Before you start up Mocha, terminate all software which uses your serial port. That includes the PsiWin server. There should be no 'wiggly thing' in your system tray, not even the straight line. The PsiWin server should be stopped.

You will see a screen with setup information. Choose the correct serial port. Select the Win CE machine, preferably at a speed of 115200.

The top of the settings screen of Mocha

If Mocha can use your serial port freely, it will not give any error messages, but it will wait for a connection to your 'Palm', which is in this case a Psion.

Setting up the Psion

You should define a new modem and a new Internet Service Provider on your Psion. I have a Dutch 5mx, so I cannot provide you with the right screen shots, but both settings are in your Control panel, under 'Modems' and 'Internet settings'. Users of the 5 classic should have Message Suite installed.

Modems

Go to the configuration screen, tap on the modems and select the option 'New'. Settings are as follows:

Modem

Name: Mocha connection
Speed: 115200 baud
Connect via: serial
(IR-connection with your Windows laptop is also possible under W98)
Fax class: Auto (you cannot fax anyway)

Options

Since Mocha does not use a loudspeaker, you can leave these settings as they are.

Initialisation

All strings should be empty

Advanced

Flow control: none
Terminal detect: ticked
Carrier detect: ticked

Modem Type: fixed line (this option does not exist on a 5 classic)

Internet

Save your modem settings, go to the Internet settings and choose 'New'.
Choose the Based upon: Standard settings and press OK

Settings are:

Service

Name: Mocha PPP
Connection type: Direct

Account

Manual login: ticked

Adresses

Get IP address from server: ticked
Get DNS address from server: ticked

Login

Use login script: not ticked

Advanced

Enable PPP extensions: not ticked
Allow plain text authentification: ticked
Use call back: not ticked
However, if Mocha is malfunctioning, you might want to experiment with the Advanced settings

Press 'Done' once. You are now back in the Internet service settings screen.

Show connection dialogue: ticked
If idle, stay online for: 1 hr
On exit, stay online for: 1 hr

If the Psion decides to disconnect itself, it thinks, it has been disconnected from the internet, but it has itself merely disconnected from your computer. If it wants to reconnect to the internet, it will get Mocha into trouble. To prevent this, the Psion should not disconnect when it is idle. That is why you should set these settings at a fairly large time.

Getting online

It is advisable, that you already have an internet connection from your computer. This can be a dialup connection, but I use a LAN for example. It does not matter. If your Windows webbrowser and e-mailreader can make a connection, Mocha can usually do this also.

Connect your Psion with the PsiWin cable to the computer. You can use your cradle for your Revo (Plus)/Mako.

Whenever your Psion wants to make an internet connection, a pop-up screen will appear. Choose the Mocha PPP internet service and the Mocha connection modem and press OK. Your Psion will try to connect to your computer. As this occurs, you will see on the Mocha window, that it has established a connection and that bytes are flowing to and from your 'Palm'. You will now have an internet connection available for all of your Psion programmes.

Known issues

• Mocha is designed for Win95 and Win98. It can work under Win NT and Win 2000 if your sysop lets you install software on your terminal. I have received a message from a Win NT4 user who uses Mocha. As a plus, Win NT and Win 2000 have their own 'Mocha' built in. It is called 'RAS server' and you can find similar instructions to set up 'RAS server' for the Psion on the net. Be OS and Linux have similar programmes built in. I tested Mocha on a Win95 486DX4 laptop.
• If your Psion disconnects itself, you should exit Mocha and restart it. If you don't do that, the connection will sometimes be very sluggish after reconnection.
• Your Internet Service Provider and/or your LAN network director will provide your computer with a unique IP address. Mocha builds another LAN network between your computer and your Psion. However, your computer and your Psion will have the same IP address for the outside world. This can sometimes cause problems.
• As a result of the IP address problem, normal FTP will not work. You can set your Psion FTP client to 'passive' FTP. On RMR FTP this is possible under the advanced settings. My FTP client works in passive mode splendidly.
• Most problems with Mocha happen because there are still other programmes active on your serial port.
• The Psion WAP browser shows erratic behaviour. It constantly tries to disconnect and to reconnect, because it doesn't like the profile (you can choose which ISP you use in your profile and you should use the Mocha PPP profile). At the moment, I have not found a solution for this.
• If you run into any trouble, you could consider to lower the speed to 57600, both in Mocha's settings and in the Psion modem settings

Ofcourse, you use this programme on your own risk. It works splendidly with my machines, but I cannot guarantee it works for you. In fact, the makers of Mocha (Mochasoft) do not give official support to Psion users, because they do not know the specific 'ins and outs' of the Psion machine. You are free to contact me in case of troubles, but I am just another Psion fan and I am in no way connected to the Mochasoft company.
