Claim 7:
8. A method of transmitting data and command through RS232 serial port, incorporated with a server-end device and a user-end device connected through an RS232 serial port, comprising:
a) controlling a first counter to accumulate when receiving data transmitted from the server-end device, wherein the first counter is synchronized with a second counter in the server-end device;
b) storing a control command to a command queue when the control command is going to be sent to the server-end device;
c) re-executing the step a) and the step b) before the count of the first counter reaches a triggering threshold;
d) transmitting the control command stored in the command queue to the server-end device when the count of the first counter reaches the triggering threshold; and
e) after the step d), clearing the first counter and re-executing the step a) through the step d).
