USBClient is not able to recieve large chunk of data...Please Help Regarding This!!!!

Hi ,


I am using BlackBerry Desktop API's (USBCLient.cpp) on the desktop side to acess the data which is sent by USBDemo app on Blackberry device side.. The problem is it works fine when i  send simple messages such as "Hello from PC"  "Hello from Device " and so on but   when USBDemo app send large chunk of data (such as a xml data nearly 3000 bytes)  USBClient recieves only limited data.It does not recieve the whole data...


Anyone Please Suggest a solution for the same.

Split your big data block to the sequence of smaller blocks and send them one after another.

While I'm trying to get source code for the old DB we had on our Z-80 computers in high school, I'll also find the code

to drive the UART for the RS-232 connector...

But, yeah, often serial port buffering can be an issue.
