What do you mean exactly? Do you want to write a value in hex to the
RS232 port (e.g. write 26 [decimal] as "1A")? If so, just use string
>>> "%02X" % 26
Or do you want to send a byte for which you know the hex
representation (e.g. send "1A" as ASCII 26)? If so, use integer
conversion & character value conversion:
>>> chr(int('1a', 16))
If it's more complex than that (values larger than 255, etc.), the
"struct" module may help. Post more details for better help.
