Thompson/RCA DCM425C Flashing -- Linux snmp bash script

[usitsupport]

Thank you drewmerc. I switched the Vcc with GND in my earlier attempt and fried my earlier USB TTL.

Anyway, Now I managed to get to the console, but never managed to get the "p" options to response. I do get the full menu after umpteen times (maybe 30 times) by shorting pin 1 & 2 of flash. I got to "CM/DocsisCtl>" and issued:

dload -i1 192.168.100.TFTPServerIP haxorware11rev39-DIAG.bin

The Solarwinds TFTP server keep saying:
binary, get file name: X:\haxorware11rev39-DIAG.bin, file 1181284
binary, dropped because peer didn't response.
(firewall is off)

FYI: help listing
