Hi there,

Just wanted to send AT commands to an external device. Have tried TTY
and vxHpc but having no luck. Is there some trick to it that I am not
doing correctly? I don't get any replies to my commands except when I
plug in and unplug devices.

I have an IPAQ with windows CE.

Many Thanks
Gareth Gray

Gareth make sure you are using the correct terminal emulation in vxhpc. I
find that vt100 works well for just about everything I connect to (cisco
routers, intel switches, smartcards, etc). I input the terminal emulation
in the "Terminal ID" option listed on the telnet tab in vxhpc.

Also make sure you have the correct port selected... note that you
cannot select a card modem or other i/o card until after it is inserted.

Along with the other two suggestions, make sure you have the correct cable.
The usual serial sync cable is a null modem. You might need to add a null
modem to straighten it out.

Hello there,

Thanks for the replies. I tried the null modem idea and got an instant
connection screen pop up on the unit. It connected as "115200 default"
connection. But the terminal emulator is till not working.
The item i'm connecting to has a 9600 baud so I'm not sure if this is
interfering with things or not. The TTY software does have the settings
set up right however at 9600 baud. The only response I am able to get
from the item is a square on the screen when I disconnect and reconnect
again. Does this sound familiar?? I have tried all sorts of settings on
the TTY emulator and still no luck. Almost there I think, at least I am
connecting now. I wonder if it is active sync that is causing the
problem? Any ideas?
Gareth Gray.

The message you describe is activesync... close activesync and continue.

strongly suggest using vxHPC as it is a fully featured terminal
program... can't help with tty as I don't have it.

More details such as what the "item" is and details about the cable
would help.

Hello Beverly,

I've tried disabling active sync but that doesn't work. I'll try vxHPC
again. TTY is much more basic but should haveenough for me. The "item"
is a "serial port extender" by name, we use them for environmental data
transfer from field sites back to base using GPRS technology. It is a
standard nine pin RS232 connection 18-1, 9600 baud.

Thanks
Gareth

Sorry for my frustration, but it is really hard to divine what's going
on long distance without a lot more information. "Serial"
communications is subject to any part in the "series" being out of place
or wrong stopping any communication.

It _sounds_ like the device is establishing communciation on the wire
before the communication software being started and that _will_ wake up
activesync to attempt a sync connection.

It also sounds like you are assuming that you can establish a dual
connection... from the device to the com port to telnet to a cellular
connection... that would complicate the equation well beyond a simple
terminal program.

Please post the _exact_ steps and sequence you use from beginning to end
in your attempts to establish a com session.

Beyond that, it still doesn't sound like you have the wire and/or the
communciation parameters set correctly. The best way to do that is to
start hyperterminal on the PC, use a serial sync (null modem) cable and
establish a communication session with TTY _using the same parameters as
the device until you can type back and forth and see clear text on both
screens. Remember that you will have to switch back to a com (non
serial sync) connection when you return to the device.

You might also go into activesync on the ppc tools/options/enable and
uncheck it at least for the initial test phase.

1. I connect to the device and I get a 'windows' window pop up on the
screen telling me that I am connecting at 112500 baud, this is before I
have even started vxHpc. I only need 9600.
2. So I must have the right com port and I do need the null modem
adapter in the link.
3. I get the feeling that the baud set by windows on the ipaq is
overridding the baud set by vxHpc.
4. When I remove the cable from the serial port extender I get a square
on the screen, so the baud must be the problem but I have no way of
changing it.

I had written a huge message explaining exactly what I had been doing
but it got lost in logging in somewhere.

my sincere apologies, but I am personally unable to discern from any of
your posts (i.e. I have no idea of the exact steps you are taking, what
apps are running on which machine) and where (i.e. what processes) the
messages are coming from and what (i.e. the full and exact contents of
those dialogues.) We don't even know exactly what device you are using
and the os version it is running.

There is not enough information for me to patch together any picture of
what is and has transpired, so I am, unfortunately, unable to provide
any help.
