Abstract
A method, a baseboard management controller (BMC) and a system for establishing a serial-over-LAN connection are provided. The method includes: receiving data from a server unit using the first UART at a current baud rate; detecting the current baud rate of the first UART using the BMC; configuring the baud rate of the second UART of the BMC as the current baud rate; controlling the second UART to retrieve the data from the first UART at the current baud rate using the BMC; and sending the data to a network using the BMC.
Claims11
A method for establishing a Serial-over-LAN (SOL) connection, comprising:
- receiving data from a server unit using a first UART at a current baud rate;
- detecting the current baud rate of the first UART using a baseboard management controller (BMC);
- configuring the baud rate of a second UART as the current baud rate using the BMC;
- controlling the second UART to retrieve data from the first UART at the current baud rate using the BMC;
- and
- sending the data to a network using the BMC,
- wherein the step of detecting the current baud rate of the first UART using the BMC includes:
- configuring the baud rate of the second UART as an assumed baud rate using the BMC;
- controlling the second UART to retrieve a first set of data from the first UART at the assumed baud rate using the BMC;
- determining a switching range of the first set of data received by the second UART;
- determining whether the switching range of the first set of data equals 1;
- and
- if so, determining that the assumed baud rate is the current baud rate.
