cmdchr  Configuration escape character and guard time (user defined) 
This command allows the user to specify the ASCII value used for an escape 
sequence, and the pause time either side of the escape sequence. The default 
escape character is the ‘+’ symbol (ASCII 43). The default guard time is 1 
second. 
The guard time (second parameter) does not need to be specified if only 
changing the escape character. However, in order to specify the guard time, the 
escape character must be given first, as in the following example: cmdchar 43 
100 
Command format: 
cmdchar [c [n]] 
where: c = 
[32-127]  This value determines the escape sequence character 
used to enter configuration mode. 
where: n = 
[50-255]  This value determines the guard time either side of the 
escape sequence. 
signon    Display sign on message at power up 
This command enables or disables the sign on message displayed when the 
radio modem powers up. It’s main use is to indicate the radio modem is 
working, especially when it’s being connected and used for the very first time. It 
serves no other purpose and should therefore be disabled after the radio 
modem has been configured. 
The welcome message, when entering the configurator, is also not displayed if 
the sign on message is disabled. 
The only time this sign on message is not displayed (when enabled) is if 
RTS/CTS flow control is enabled and the CTS line has not been asserted by 
the host. 
Using the default command to reset the radio modem configuration to factory 
defaults will enable the sign on message. 
Command format: 
signon [s] 
where: s = 
on  Enables the sign on message to be displayed when the radio 
modem powers up. 
off  Ensures the sign on message is not displayed when the radio 
modem powers up.
