I have download the RSComm(version1.0) I tried to send a string : 01 01 00 AB etc. to the com port. MSComm are able to send and receive the Ascii caracter 0x00, but the RSComm Control can only receive the Ascii 0x00 Dit anyone had the same problem with this control? Makes my Laptop(win98) quite unstable as well...
