    CY8CKIT-042: UART problem


      Dear All,


      I am trying to develop MODBUS SLAVE on CY8CKIT-042 board. I have written simple program initially to transmit whatever received. Code works when I type on Hyper terminal nicely. But when I send MODBUS frame through Modbus testing software (I tried two diff. s/w), software gets hang.


      When I shorts two pins (RX- P0_4, Tx- P0_5) on PSoC 5LP I/O Header (J8) , board transmits whatever I types on Hyperterinal. But Modbus testing softwares gets hang.. Testing software works fine on PC UART ports.


      What could be the problem ?


      Thanx in advance
