Service Software Instructions
General
The service software is specially designed to facilitate the servicing of PCS cel-
lular telephones.
The software can be used to control the phone according to the user’s wish
merely by entering commands via the keyboard of a PC/AT connected to the
phone.
This section refers to PCS Service Software Version 0.1 To receive a free up-
grade, please follow the de–install instructions in Appendix I and send the disk
to Nokia Mobile Phones.
Required Servicing Equipment

Note: A number of PC’s of an older generation use the Intel, National Semiconductor, or
United Microelectronics IC 8250 as the serial port UART. This is a comparatively
inefficient circuit for current purposes and does not necessarily support the
M2BUS adapter at 9600 baud. The newer UART’s NS16450 and NS16550AF of
National Semiconductor offer solutions for these problems.
