I have a VB program using MSCOMM32.ocx. When a DC2
charactor is received via com port, I send out a text
string on the same com port. If the user is editing a
cell on the worksheet, the MSComm1_OnComm event
comEvReceive does not activate. If a cell is not being
edited everything works file. Does excel stop executing
the VB program is users are editing a cell.

thanks in advance.
