[Lazarus] One last ask for help

I wrote an application for WinCE in Lazarus 0.9.30/FPC 2.4.2 some time ago. Finally appear a customer interested in the system. It was tested in an iPaq equipment during the development stage. Late I tested it with a Motorola ES400 handheld when I can test the functions using a barcode scanner. Everything were alright. I have the idea that my software were ready to sale even if the customer wants to use barcode scanner as data entry for some fields in my forms.

Based on this I offer the software for the mentioned customer and tell him that it always have to rent(or buy) a handheld with windows mobile 6 or greater.

He gave me, last friday, an handhelp Intermec with windows mobile 6.1. The model was Intermec CK3a1. I installed my software in the equipment and it ran ok as expected, since it have a arm processor and windows mobile 6 or later. Next step was test the program reading barcodes via CK3a1 barcode reader. Then I go to hell. The CK3a1 read the barcode as indicated by the sound an the pilot light but nothing appears in the correspondent Lazarus edit box. I spent all weekend trying to learn what was wrong. Monday, very ashamed I told to the customer that the program was not running Ok with Intermec CK3a1. In the monday I tested with another Intermec, the CN50 model and the same error occurred. I tried with an old HP handheld and an external barcode reader attached in the slot of the HP and everything was right. The barcode read was successful.

The customer call the firm that rented the equipment and it offers to substitute by a Cipher CP30. After a long time of tests I discover that if I open the "barcode" software(it comes with CP30) and use the barcode reader with my program, the barcode was read, but the first character of the barcode is left. The rental firm people try lots of combinations of configurations in the Cipher CP30. And the problem persists.

This afternoon the customer give me an ultimatum. If the software doesn't run with a correct codebar reading they will change to another program.

In all cases, if I install a .net(wrote in C#) in the handhelp, the barcode is readed and is readed correct.

Well people. I know that you have no duty to help me. But once more I ask for help with this problem. I believe in the same dream you believe: Write once, compile everywhere. But I still believe that the code generated will run as expected.

No one in the Lazarus community can help me? Why I wrote in the mailing list, english forum and portuguese forum and nobody answer?

If the ,net application and even the windows mobile application "note" read the barcode correct, is them wrong or is there something wrong with the way Lazarus and FPC talk with the WinCE(windows mobile 6 or later) I/O routines? Will WinCe change?

Here are now 11:33 PM. I have 'till 12 AM tomorrow to tell something to the customer. 

Look here the potential customer I'll lost: http://www.votorantim.com.br/en-US/Pages/home.aspx

Think about the visibilty Lazarus, would acquire.
