Connecting a "Hayes compatible" external modem to your Psion

To connect an external modem to your Psion, you require:

1) The PsiWin Serial cable

2) Null Modem adaptor *(see note below)

3) Gender changer

4) Depending on the connector on your modem, a 9-pin to 25-pin serial adaptor.

Psion produce the "Psion Modem Adaptor" which replaces items 2, 3 & 4 above. Cost is about ten pounds in the UK and it can be obtained from Clove Technology or Widget Software.

Optionally, a "non-Null Modem" lead to go directly between the Psion (exept 3a & Revo) and the modem can be obtained from www.serialleads.co.uk

Normally, when connecting an external modem with the PsiWin cable, you should disable "Carrier Detect (DCD)" in the modem settings.
*Note: It is important to use a null modem adaptor which has all pins connected. Some generic adaptors / cables intended for PC use do not have all pins connected and will not work with the Psion.
