Vendor not answering probably SBC is very old. I really need help with this. Only things is printed on the board is TTM-SA2, 94V-0 (see attached). I understand this looks like a challenging project but keep in mind solving normal issues is not a big thing. It is big when you solve an unsolvable challenging problem.
Device software has an option which can read information I need and display these information on the computer monitor but there is no way of saving these info into a file. I want to save these information in a file as a backup and keep it for the future when device needed repair and loading these info into the device again.
I also tried to log info via "serial port monitor" when I use this option to read the information. This was successful and I can see information I need are there.
I can connect to the device via rs232. I am looking for a way to send commands to the device to read info from a certain address of the memory and to be able to write it back into the same address. I think I can find the address of the info I want from "serial port monitor" log. Now I need to find a tool to be able to read info from that address in binary and write back using the same tool into the same address. Is this possible? If so what tools are out there to help me with this?
Device software uses IRP_MJ_READ command to read info I want (see attached log). May be I can use IRP_MJ_READ and IRP_MJ_write commands to read and write info I want directly. Any advice in this?
103 IRP_MJ_READ - Transfers data from a COM port to a client (COM4) - 349 bytes of 349
