BL2100 + RABBIT 2000 NO WAY TO USE TERA TERM OR NETWORK

Hi all,
i’m using Dynamic C 9.62, have downloaded the download.bin to the unit using the serial port, cycled the system in run mode.
I can download programs to the unit using the serial port but i cannot communicate with the unit using the tera term or hyperterminal nor cannot access the unit using lan.
I’ve tried all possible combination: crossed cable, hub, switch… no way.
I’m wondering if with this unit is possible to remotely dwonload software trough the lan or what’s going on… unit too old? software too recent? must use an older version of dynamic C?
What the hell?

Thanks in advance.

Try running the sample program BL2100\rs232\relaychr.c
