Mobile Apps - COM1 Serial for Hyperterminal

Asked By jp2code

28-Mar-07 10:01 AM

Is there a way to test a serial connection on a PPC using HyperTerminal
(HT)?

Another application that we want to use BT and/or IR with is having problems
talking to our device, so we thought we'd do a quick check to see that we
knew how to talk - using HT.

Apparently, we don't!

No one here can seem to establish a connection with HT. We have a plug on
the bottom of our PPC that converts to a Serial DB9 connection, but HT can't
connect, and the PPC doesn't seem to have a way to establish a connection
using a serial connection.

Is a program required to open this port, or should it be something simpler?

You're sure you have the connector right (not nulled or anything)?  You
should be able to communicate from the device to HT just fine.

The cable is one of those that comes with the device for sync-ing with a PC
using ActiveSync.

I don't want to use ActiveSync, because I want to test that our connection
methods are working.

My HT settings on the PC are:
COM1, 9600 baud, 8 data bits, no parity, 1 stop bit, Hardware Flow control,
Emulation: VT100

My PPC has spit up 2 Notification Error messages: "Cannot execute
connmgr.exe" and "Cannot execute repllog.exe" - if that helps at all.

Does the PPC need a special tool to connect with HT, should it echo what it
receives from the PC, or do I need to come up with some other method of
working with the device?

What are the settings on the device?  As long as they match you should be
fine.  Not sure if the port supports flow control - that's hardware
dependent.  I'd try no control for now.


You need to make sure ActiveSync is set to not use the serial port on the
device or it will hold the port.


Echo where?  You have to have software on the PPC running that opens the
port and listens.  It would do whatever you code it to do - if that's to put
the data on the screen then so be it.  The PPC doesn't do anything like that
automatically, just like your PC doesn't (you run Hyperterminal to do it).

I can't find any "serial settings" for the device. Any idea where this would
be located?


PPC doesn't have a HyperTerminal style program, so I don't know where to
look to see if data is getting to the devices serial port.

Is it even called a serial port on the PPC? When I open the Connection
Settings, I see the following:
* Beam
* Bluetooth
* Connections
* CSD Line Type
* GPRS Settings
* Network Cards and
* WLAN

Before I can connect, I need to know what to use to connect to the PC with
on the device side.

What should I use, and how would it be set up?

ActiveSync->Settings->PC->Options


That's my point.  You need software on the PPC to do this, just like you dop
on the PC.  You either need to find or write some software to meet your
needs.  How it's set up is going to be dependent on that software.
