[irda-users] IBM T22 Thinkpad Nokia 6310i and GPRS

[Hugh R. <hu...@ci...>]

I am having a problem with GPRS connection. The T22 terminates the call
GPRS connection after just over 2 minutes.

I've been using GPRS for well over a year, so I know what to expect.

I've checked Alessandro Suardi's problem of 2002-11-02.
Is this a kernel problem I've encountered, and should await
Suse upgrade to 9.1 (I gather shortly)

Configuration:
IBM Thinkpad T22 with IrDA enabled.
384Mb memory
Dual boot with XP professional.

Suse Linux 9.0 (Linux Kernel 2.4.21-202) - kept up to date.

Symptoms:
GPRS session starts OK.
Can receive pages from various web sites (via Opera 7.50)
Session terminates after 2.10 minutes
(with varying amounts of data received)
See dial-up log below from kinternet)

What does work
==============

Suse Linux 9.0
1) Can do dial-up with the same phone using a traditional
GSM call, and all works fine - I tested for over 10 minutes.

XP
1) Can do GRPS session OK - tested for over 20 minutes, and
over 1.2 Mb received.
2) Can do dial-up with the same phone using a traditional
GSM call, and all works fine

What I have adjusted to see if gave any joy - but didn't
Appear to affect
1) Baud rate between the IrDA port and the 6310i

Many Thanks in anticipation
