talk to Motorola 6288 phone and go GPRS with infrared

[Zhang Weiwu]

Hello. I am running 4.9-RC2 on my Thinkpad R30. I wish to connect my 
motorola 6288 phone and connect to the Internet with the phone's GPRS as I 
used to do in Win2k. (Oh, I guess I am really too dumb to work such thing.)

I got a Motorola Timeport modem script for Mac OS which is clear formatted 
that I thought perhaps can be a reference in build a kermit.dial in 
FreeBSD. 

When the notebook was running Win2000, in the device manager there is an 
infrared port and a serial port (COM1). I ran IrComm2K to enmulate a COM4 
which is actually the infrared port, and ran the modem drive (timeport 
drive is okay) on COM4. The notebook actually have no serial connector, 
COM1 i guess is for a docker.

First I think I should figure out what is the correct device to let birda 
to connect to. 
In BIOS infrared port is set to 3F8 IRQ4 DMA1. dmesg shows that

sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0
sio0: type 16550A
sio1 at port 0x2f8-0x2ff irq 3 on isa0
sio1: type 16550A

where in kernel config file it is:

device sio0 at isa? port IO_COM1 flags 0x10 irq 4
device sio1 at isa? port IO_COM2 irq 3

and there isn't option PNPBIOS.

Then I disabled serial port in BIOS, dmesg changed to:

sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0
sio0: type 16550A
sio1: configured irq 4 not in bitmap of probed irqs 0

So seems sio0 is the infrared port, but I still don't know which is the 
device in /dev for the infrared port or kermit. I tried
# irs -d /dev/ttyd0
and send a business card to the notebook. The phone complained no device is 
found.

Do I actually need birda when all what I want is to dial-up to the Internet 
with the phone? Am I  still very far from success or just a little? Thank 
you.
