Return Codes for Receive Only
The Receive Only return code is the status sent to the host
computer. The wireless station returns data and the ex-
tended command’s status to the host computer in the fol-
lowing format:
\\X\CC\DATA<CR> or \\X\CCCC\DATA<CR>
“X” is the return code listed in the following chart.
“CC” or “CCCC” is the character count of the received data.
“CC” is 00--99. “CCCC” is 100--2000.
“DATA” is the RS-232 data received from the RS-232 device
attached to the wireless station (if any data was received).
The wireless station simulates the [Enter] key to return the
code to the host.
