与DELL扩展坞一起使用时，设备工作缓慢 [英] Device working slow when used with DELL Docking station

问题描述

我正在使用DELL Latitude笔记本电脑(具有Inbuit串口)..

我也有一个DELL E-Legacy Extender(一个外部扩展坞，它为我提供了另一个通讯端口)，用于连接第二台设备.

请参阅有关DELL E-Legacy Extender扩展坞的链接的详细信息:

我的问题:
通过笔记本电脑的内置com端口连接的任何设备的运行/操作速度均比-通过扩展坞连接同一设备时的运行/操作速度更快.

I am using DELL Latitude laptop (which has an inbuit com-port)..

I also have a DELL E-Legacy Extender (an external docking station which gives me another com-port) to connect a second device.

Please see link for the DELL E-Legacy Extender docking station details:

My problem:
Any device when connected via in-built com port of the laptop runs/operates faster than - when the same device is connected using docking station..

Any suggestions, comments on this??

推荐答案

9600很慢-20年前很慢，所以现在很冰爽:)所以呢?可能不是这样-我更倾向于看看您正在使用的流控制以及扩展坞上使用的UART设置...

如果您在Windows下运行此程序，请查看设备管理器"中的com端口.

如果您正在重击金属，则必须回顾流控制以及如何处理UART FIFO缓冲区

9600 is slow - it was slow 20 years ago, so it''s positively glacial now :) so it''s probably not that - I''d be more inclined to look at the flow control you''re using and the UART settings used on the docking station ...

If you''re running this under windows then have a look at the com port in the Device Manager

If you''re metal bashing then you''ll have to review your flow control and how you handle the the UARTs FIFO buffers
