Important information for the use of Mobile ISDN-Controller M2 under OS/2:

AVM does not deliver any guarantee or support for the M2 PC-Card for the use under OS/2.
The supplied OS/2 drivers for the M2 PC-Card can be used at own risk.

In case of a conflict while installing or loading AVM gives a hint under reservation:

Notice:
"ISDNLOAD: Fehler bei der Installation
ISDNLOAD: I/O Adresse 0x150 und Interrupt 5 nicht verfügbar
Weiter mit beliebiger Taste"

The conflict is caused by some PCMCIA hardware enabler, that already allocates the 
IO space. The conflict can be worked around as follows: install the driver for the 
Mobile ISDN-Contoller M2 without inserted M2 PC-Card and boot the system. Insert the 
M2 PC-Card and load the driver of your choice (GSM S4 / GSM S10) manually. From now on
the PC-Card can stay inserted.
If the driver can not be loaded, the PC-Card must be pulled out and inserted again about 
five seconds later. Now the driver can be loaded again manually.
If this doesn't work, you can also remove other hw-enabler from config.sys. 
But first try to work with the first solution.


The self-extracting archive in this subdirectory contains the current con-
troller software. Please copy the file onto your computer and execute it.

The subdirectory .\DISK will be created.  It contains all files required for
the installation.  Please install the controller software using the instal-
lation procedure provided by your specific operating system and refer to
the readme file. If you want to regain space on your hard disk, delete
the archive and the subdirectory after the installation.

The archive contains controller software for

Controller:	AVM Mobile ISDN-Controller M2
Operating System:	OS/2
Version:		03.07-01 (ISDN)
			03.07-01 (GSM S10)
			03.02-06e (GSM S4)
Build:		99.05.31


Please check further references to product and installation in the manual.

References to the driver-version:

Changes respect to earlier versions:

1. GSM S10: New CRC mechanism in ISO3309. This allows Internet access via 
protocol PPP over ISDN. An Internet access to e.g. Cisco oder Ascend Routers
is possible if the protocol V.110 is supported. Remote Access Clients like 
AVM NetWAYS/ISDN based on Mobile ISDN driver software are now able to 
communicate via PPP oder ISDN.
2. GSM S10: fax transfer down to 2400 Baud 
3. ISDN: New CRC mechanism in ISO3309. Data reception with CAPI applications,
that fall back on the protocols X.75 or HDLC transparent with automatic CRC 
recognition and transmission with configurable CRC.
4. ISDN: Extension of the protocol stack because of the call number length,
automatic overlapped sending at numbers > 25 length. New telephone provider 
possibly generate longer numbers because of the net code.
5. ISDN: Special protocol 'FritzServer' autodetection X.25/X.75 inserted 
(for IDTrans/EFT server mode). Supports new FRITZ!data funktions 
at server mode.
6. ISDN: In case of outgoing data-calls to GSM (M1, M2 or FRITZ!GSM) with 
CAPI-aplications that fall back upon the protocols X.75 or HDLC transparent 
(e.g. FRITZ!data) a `m` or `M` has to be added to the call string.
