1.1 Issuing a Set-Line-Coding Command During an Active Data Transfer Can Cause Data Corruption and/or Data Loss

Issuing a set-line-coding command while a data transfer is in progress can cause data corruption and/or data loss. The set-line-coding command configures serial line parameters such as baud rate, stop bits, parity, and data bit width. If this command is received before the current data transfer has completed, the device may apply the new configuration mid-transfer, resulting in one or more bytes being corrupted or dropped.
