Hi,

I'm developing a Java Application which is able send out SMS

Right now, this application needs to be deployed into AIX 5.3

Previously I was using RXTX Serial Comm for Sun Solaris, RH Linux and Win2k
When it comes to AIX, I'd discovered not much info can be found in the web

Anyhow, I'm trying to setup the GSM Modem in AIX 5.3 first

What i'd done here is
1. connect the Machine with the Modem
2. smitty tty -> add tty -> tty rs232 asyn terminal
-> sa2 available 01-S3 standard I/O serial port
3. Baudrate 115200, Parity None, Bits 8, Stop Bits 1, Flow Control RTS(Hardware)

This is the parameter after set, tty=/dev/tty2, paranet adapter=sa2

Finally, when i insert the command "stty < /dev/tty2"
Suppose i can get a "OK" response from GSM modem, but anyhow i didnt get any of it
I'd follow the parameter setting provided by Wavecom M1306B technical spec

Please help

Thanks

If you have a power 5 machine (p5xx - 91xx-5xx) the built in serial ports are not fully functional "serial ports" they DO NOT SUPPORT RS232, they are limited to console or console over modem connections, so don't bother until you have a proper RS232 card installed.

lsconf | head
should tell you if it is a 91xx-5xx machine.

You can also only configure p5xx serial ports via the ASM inretface, the smit screens do not work properly.

Hi,

Thanks for the reply

The System Model is 7028-6E4

How am i gonna know that is the machine support RS232 or not?
Is there anyway i can get the technical spec?

Thanks

Hi,

I'd checked with the IBM spec
http://www.openbase.co.kr/customer/pds_files/IBM_spac_031125.pdf

IBM eServe pSeries 630 (7028-6E4)
According to the document, it shows that this machine support EIA RS232D connection

Hi,

This is what i'd tried

The IBM machine model 7028-6E4 consist 3 physical serial port (sa0 - S1, sa1 - S2, sa2 - S3)

To make life easy, I only create a tty0 point to sa0 using smitty

smitty tty
-> tty rs232 asynchronous terminal
-> sa0 Available 01-S1 Standard I/O Serial Port

I'd followed the parameter setup given by technical spec of WaveCom M1306B.
http://www.jandrew-elec.com/m1306b.pdf where

baudrate - 115200
parity - None
data bit - 8
stop bit - 1
flow ctrl - rts (hardware)
Initially we suspect it could be the modem problem, but it works in Window 2000 server

Anyway, let's move to the next part

I'd vi /usr/lib/uucp/Devices file and uncomment the line below
Direct tty0 - 115200 direct

PS: I even tried this
Direct tty0 - Any direct

After that, I try to connect to the modem using this command
cu -ml tty0

and this is the response the machine gave
cu: 0835-028 The connection failed. CAN'T ACCESS DEVICE.

Well, so I tried to chmod the /dev/tty0 to 666
But once i did it, and cu again, it just hung there and no "connected" message prompt out

Have i miss up some steps?

Please help

The problem solved,
I think it's because of the machine's driver problem
When i change to another AIX machine,
Connection success
Anyhow, will further investigate if it's really because of physical machine problem

Suggest you get a serial breakout box to make sure the signals on both ends are right. With a modem you should not need a crossover cable.
