"I'm not sure what you mean by the UC sending/receiving in "hex" format. Anything can be represented as hex. "


I only meant that computer represents numbers by ASCII value. If 5 is directly sent by computer, microcontroller will take it as 53.


"If UC sends data 234 as 8 bit data, what will be the output of instruction:
Text1.Text =MSComm1.Input ? (ASCII character of '234' or '234')
It will be the ASCII character 234"


I want to dispaly same value that is sent by UC.Then what is the way to display 234? The following instruction did not work:
Text1.Text=Asc(MScomm1.Input)
