Dear Experts, Need some quick reference code in assembly which are supremely compact in size wise (as size of code is a big constraint now, so assembly is also the last option) used to convert an incoming serial ASCII line of digits to hex codes for computation. Roughly 4 ASCII digits, e.g. in ASCII: (31h 32h 33h 34h) to be read as 1234dec OR 4D2hex. Appreciate some really good helping hands! Cheers, James
