INSYS Modem contains a flash EPROM which allows a firmware update without hard-
ware manipulations. The latest firmware can be requested from your service partner. It 
consists of the flash loader (file HS_LADER.s37) and the firmware code (file with exten-
sion .S37).  
The update is executed by a terminal program, which can perform an ASCII upload (ASCII 
text transmission protocol), running on a PC. Tested an recommended terminal pro-
grams are TeraTermPro, ProcommPlus and HyperTerminal (included in Windows). The 
following settings in the terminal program are mandatory: 

• 

hardware handshake 

• 

no interpretation of characters like tab stop, line feed, carriage return, backspace 

• 

baud rate between 9.600 baud and 57.600 baud  

The upload procedure takes 2 to 3 minutes at 57.600 baud, , longer with lower baud 
rates.
