Hi Dag,
hi IrDA experts,
I have a problem transfering larger Files (> about 2kb) to and from my PowerBook G3
via IrDA.
Configuration:
==============
Hardware:
Macintosh PowerBook G3 (bronze keyboard)
Kernel:
Linux linuxpb 2.2.18 #1 Wed Dec 20 16:42:41 GMT 2000 ppc unknown
irda-utils:
irda-utils-0.9.14
setserial info:
------------------------------ [ BEGIN ] ------------------------------
/dev/irda, Line 1, UART: unknown, Port: 0xd080e000, IRQ: 16
Baud_base: 0, close_delay: 50, divisor: 16
closing_wait: 3000, closing_wait2: infinte
Flags: spd_normal
------------------------------ [ END ] ------------------------------
External IrDA devices:
- Palm V OS 3.3
- Ericsson MC218
psBeam DEMO version 1.10F installed
- Ericsson T28s phone with DI28 IR-modem
Symptom:
========
1. HotSyncing Palm V with PowerBook G3 running MacOS 8.6 and Palm Desktop software
via IrDA works fine.
2. IR (OBEX) transfer between PowerBook G3 running Linux and Palm V works for
Calendar data and VCF-Cards (addresses). Tool: "irobex_palm3"
3. IR (OBEX) transfer between PowerBook G3 running Linux and MC218 Organizer works for
Calendar data and VCF-Cards (addresses).
4. IR (OBEX) transfer between Palm V and MC218 Organiser works for
Calendar data and VCF-Cards (addresses).
5. IR File-Transfer between Palm V and MC218 works fine.
Tested a file with 103000 Bytes from MC218 to Palm in about 35 sec ==> 23 kBaud.
6. IR File-Transfer between PowerBook G3 running Linux and Palm V interrupts after
some 10.000 bytes. Works sometimes after some retries but is very slow.
7. IR File-Transfer between PowerBook G3 running Linux and MC218 Organizer
interrupts after some 1.000 bytes. I managed to transfer a file with 48000 bytes
in 53 secs from PowerBook G3 to MC218 ==> 7,1 kBaud.
8. I have also very instable sessions when I use TCP/IP from MC218 to the Linux
PowerBook (eMail and Web via local "ppp" tested). It works, but is very slow
and I need many retries.
I got a lots of "kernel: Framing or parity error!" in "/var/log/messages".
I don't understand the following entries from Syslog (see below):
- "kernel: irlap_change_speed(), setting speed to 0"
- "kernel: irlap_change_speed(), setting speed to 9600"
Questions:
==========
It seems for me that IR-discovery works with 9600 baud. But somewhere in the
communication session the speed has to change for data transfer to 57600 or
115200 baud.
Q1 How does speed change work?
Q2 Where in the communication process is this?
Q3 Is there a problem with my settings or the IrDA driver?
Q4 What does "setting speed to 0" mean? This is normaly a "modem hangup" ?!?
Q5 How can I set the speed on the Linux side?
Q6 Why are the speed settings for IR in some applications disabled? This
is for example in the "Comms" software on the MC218:
If the port is "Serial 0" I can change baud, databits, stopbits, parity,
flow control. When the port is "Infrared" I can adjust nothing.
When I watch "/proc/net/irda/irlap" during a file transfer "bps" changes
really from "9600" to "0" and to "9600" again.

Note on "irpsion5": I have a problem with the mtu-size. So I hardcoded it to be 253.
