Andrew, The problem with setting S111=0 is that the telebit does it's own error checking, and with no protocol established, the effect is that it's making its own blocks and adding its own crc's. So ymodem's crc ends up in a block with the telebit calculating its own crc in addition. This dramatically slows down throughput. Better to match protocols between the machines and set 111 to support the selected protocol. Pete
