Note CompoWay/F commands use ASCII code as the transmission code. Therefore, be sure to use
ASCII code for the CompoWay/F command after the command code 2803 hex (from node number
to text) when using SendCmd or another instruction.
Example: If the CompoWay/F command MRC SRC is "01" or "02" (where the quotation marks (" ")
indicate ASCII characters), treat 0, 1, 0, and 2 as ASCII characters. Therefore, set "01" as 3031
hex (not 01 hex), and "02" as 3032 hex (not 02 hex).
Further, to write the CompoWay/F command to the command storage area by using SendCmd in
frame order (without creating empty bytes), the SID component of the CompoWay/F command
requires 1 byte of ASCII as 30 hex, so set the subsequent components in one byte each.
