i've got framing error when trying to read large amount of data. And setting the buffer size didn't help me. any suggestions ?
Am sure that the com settings are matched, I mean data larger than 4096 byte (the default value of FIFO buffer).
At 115200. no i can't , no handshaking, over 1 m, yes .
it's my 2'nd step to use ethermet. but, now i want to do it using RS232 . thanks 4 ur reply
Slow it down, use handshaking, and make sure you have a very good, shielded cable.
I rarely trust USB to Serial adapters. Just haven't had any luck with them. If you plan to go to ethernet anyways, just do it now. TCP/IP is faster, can travel farther, and is a lot more expandable.
