Example using RCOM

On the Workabout:

♦Exit from the SunData application on the Workabout by pressing ∪ +X.

♦In the System Screen, press Menu, Spec, Remote Link, and press Enter. Set the

Remote Link to On, Baud rate to 19200, and the Port to A.

♦Connect the RS232 port at the top right of the Workabout to the PC’s COM1 serial port using the SunScan comms cable.

From the PC

♦At the DOS prompt, in the directory holding RCOM.EXE, type: RCOM↵

(Let's assume this is in your C:\SUNSCAN\COMMS directory)

The RCOM prompt "»" followed by the current subdirectory name will appear, in a DOS-like screen.

You should now be able to get a directory listing of the Workabout Internal Disk on your PC by typing DIR I: ↵ at the prompt.

Note: in RCOM, the Workabout drives A, B and Internal are mapped onto drives L, R and I.

♦If the subdirectory \SUN\ does not exist you must create it as follows:

>>C:\SUNSCAN\COMMS>I:↵ >> I:\>md\sun↵

♦Check the new subdirectory now exists:

>> I:\>dir↵

♦Then type

>> I:\>copy c:\sunscan\psion\*.* I:\sun\↵

This copies both the SunData program sundata.app and sys$8087.ldd, which is also required, to the Workabout Internal drive subdirectory \SUN\ and confirms the process. When you have finished:

♦ On your PC, type EXIT↵ to exit from RCOM

♦On the Workabout, close down the Remote Link: From the System Screen, press

Menu, Spec, Remote Link, and set it to Off, then press Enter.

If the SunData icon does not automatically appear in the Psion System screen, see More Psion and file handling notes about re-installing SunData as an application.

Documentation of RCOM and SLINK

If you have been successful with the above transfer instructions, you can skip this, but if you need to know more about either RCOM or SLINK, the SunData s/w diskette contains text files in the \COMMS directory which explain the operation of the transfer programs.

•COMMS.TXT gives brief details of the operation of both SLINK and RCOM.

•RCOM.TXT is a text file containing the full RCOM manual.
