Hi,
I did use it, but I did in a far more conservative way. I use 9600 baud,
in hostile environment (noisy, industrial, long cable (about 100 feet))
even 1200 baud. It is very important to do a level conversion with a
MAX232 or similar otherwise the error rate increases. It is also important
to implement a good protocol; I use checksum and ACK/NAK quoting. Even CRC
may be necessary.
I hope this helps.
