What is the exact range of ASCII values that the mscomm control can receive correctly in Inputmodetext ?

Can binary data be correctly received in inputmodebinary , more than one byte at a time ? If yes , is there any maximum input string length limitation ?

Either mode will work in most situations. If you are using NULL characters then it may be preferable to use the binary mode. The main difference is the way the data is handled:

Dim aryData() As Byte

aryData = MSComm1.Input

returns an array of byte values representing the data that is received. This can be one or more bytes at a time (this depends on two things, 1) the value of the InputLen property which determines how many characters/bytes to take out of the input buffer on each call and 2) the size of the input buffer - if this is too small you may experience loss of data as excess characters/bytes may be discarded if not read.
