Fault
The modem parameter re-
quest function is not work-
ing or is not correct.
For example, under Win 98
with <Start><Set-
tings><Control Panel><Mo-
dems><Diagnos-
tics><More Info>
Data transmission with
Xmodem is very slow.
Laplink 7.0 is not working.
Fault
Monitor fault when Gigaset
M105 Data is active (e.g. slight
flickering or moiré effect).
A slight humming can be heard
in the loudspeakers connected
to the sound card when Gigas-
et M105 Data is active.
Cause
Windows does not follow the
AT Hayes conditions.
Technically specified time de-
lay that are not supported by
the modem's driver software.
Xmodem operates in half-du-
plex mode. The transmitting
unit waits for acknowledge-
ment after each data package.
The signal delay (20–30 ms per
data block at the DECT inter-
face) significantly reduces the
transmission speed.
Data transmission is switched
during transmission, AT Hayes
commands are not used for
this.
Miscellaneous
DECT HF wanted signals is in-
fluencing the monitor.
DECT HF wanted signal is de-
modulated by the analog com-
ponents of the sound card or
the amplifiers of the active
speakers and thus produces a
humming sound.
