I need to send data bytes without converting them in ASCII form, but the write function of luars232 is converting the data into ASCII before transmission even if I pass it to the function as a number. Please provide possible assistance. Thank you.

Lua doesn't have a `char' type like C. (e.g. 0x41 is not equvilent to 'A')
Use string.char and string.byte to do the conversion.
