Send_Strings

This device also has some special Send_String escape sequences. If any of the three-character
combinations in the following table are found anywhere within a Send_String program instruction,
they will be treated as a command and not the literal characters.
Send_String sequences
"27,17,<time in 100 microsecond increments 1-255>" Sends a break character of the specified length of
"27,18,1"
"27,18,0"
"27,19,<time in 1 millisecond increments 1-255>"
"27,20,0"
"27,20,1"

Xmodem timing commands

The following table lists the AXB-EM232 Xmodem timing commands. Xmodem timeouts and
retries exist to accommodate potential Ethernet delays and for consistency among and within
products.
Xmodem timing commands
'TIMEOUT XX'
SEND_COMMAND SERIAL, 'XMTO XX' Over AXlink; where XX is from one to 50 seconds in 1-second
'RETRY XX'
SEND_COMMAND SERIAL, 'XMRT XX' Over AXlink; where XX is from one to 10 in increments of one.
Any of the above will change timing for Axcess code download as well as firmware upgrades.
10
time.

ters to be transmitted. Used with the 'B9MON' com-
mand.
Inserts a delay before the next character to be
transmitted.
