Connecting a Psion and PC with Comms and Hyperterminal

In the PC, connect the PsiWin serial cable to a free COM port and make sure no other application is using the port.

Connect the cable to the Psion and make sure the "Link" (Ctrl-L in the System screen is set to "Off".)
 

The Psion

In the Psion, start the Comms application and in the menus - "Tools / Communication settings", use these settings:
     
 Settings Tab
     
      Use comms port - Serial port 0
      Baud rate - 115200
      Data bits - 8
      Stop bits - 1
      Parity - None
     
 Handshaking Tab
     
      RTS/CTS [X] checked, all others unchecked.

Tap "OK" and the Psion is ready to connect to the PC.
 

The PC

In the PC, launch Hyperterminal by going to "Start > Run" typing "Hypertrm.exe" (without the quotes) and clicking OK.

Give the connection a name (Psion?), select an icon and click "OK".

In the "Connect to" dialog box, move to the bottom (Connect using) line and set this to the COM port with the Psion cable attached and click "OK".

In the COM1 Properties dialog (or whichever COM port number you are using) enter settings to match the Psion's:

      Bits per sec - 115200
      Data bits - 8
      Parity - None
      Stop bits - 1
      Flow control - Hardware

and click "OK".

Communicating

You should now be connected with the Hyperterminal window displayed. Characters typed on the PC should appear on the Psion and characters typed on the Psion should appear on the PC. This in itself is a useful test to check that the Psion and PC are communicating, particularly if there are connectivity issues with PsiWin.


Transferring Files

On the Psion, tap the "Send file" button or from the menus - "Transfer / Send file".

In the "Send file" dialog, set the protocol to YModem (batch) and navigate to the file to be sent. Tap "OK" to send the file.

On the PC, in the Hyperterminal menus, select "Transfer / Receive File", select the folder for the file to be received, set the protocol to YModem and click "Receive". The file should then be transferred from Psion to PC.

To transfer from PC to Psion, set Hyperterminal to send, then the Psion to receive.

IMPORTANT - whichever machine (PC or Psion) is *sending* the file must be actively sending before you select receive on the other machine. If you set up the receiving machine to wait for a file and try to send, the transfer will fail.
