Dear Giang,

Here how you can send an ascii char from HyperTerminal.

1> if char is printable (i.e. ascii value bet 0x20 to 0x7E); you can press corresponding key (e.g. '1' or 'm').

2> if char is non printable (i.e. ascii below 32 or more than 128) follow this procedure.
.... A) Press & Hold 'Alt' key on keyboard.
.... B) Key in ascii number in decimal using NUMERIC keypad (RHS of PC Keybourd)
.... C) Release 'Alt' key now.

Mahesh
