4.2 GSERV
4.2.1 General
GSERV is a PC utility program for controlling Benefon GSM phones in the service
mode.
GSERV allows the user to check the functionality of mobile hardware blocks and
also features tuning procedures if re-tuning of the mobile is necessary, such as after
replacement of a component on the RF module.
4.2.2 Installation
GSERV can be run from a floppy disk, but it is recommended to create a new direc-
tory on your hard disk and copy all the files there. Please study the file
README.TXT on your installation floppy disk for more specific installation instruc-
tions and information on the latest changes and updates regarding software and tun-
ing procedures.
4.2.3 Starting GSERV
If your computer COM ports have a normal configuration (they probably do), you can
start GSERV just by typing:
In any other case, the syntax will be:
gserv <
port> <irq>, where:
Your computer can stop responding or crash if you specify the wrong IRQ number. If
you don’t know what it is, don’t attempt it.
4.2.4 Troubleshooting
Perform the tests below in the specified order. If one of these steps fails, fix the prob-
lem before you continue.
1. Connect phone to the service adapter and start GSERV. The green power indi-
cator light in the service adapter should be on.
