怎么使用VEE与RS232热板通信

嗨，我打算使用VEE通过RS-232与EchoTherm可编程数字热板型号HS40进行通信。
这不是符合IEEE-488的设备，因此不响应像“* IDN？”这样的SCPI命令。
它仅使用简单的单字母ASCII命令，如“a”，“B”或“c”。
我已经使用USB-RS232电缆（COM4）和Windows Hyperterminal程序成功地与热板通信，具有以下设置：2400个Bauds，8个数据位，1个停止位和无奇偶校验。
我的问题是如何让VEE通过RS232与这个热板通信？
：？：我尝试将I-O库使用了Instrument Manager，但没有成功。
Agilent I / O库甚至无法检测到热板。谢谢您的帮助！

  Hi, I'm planning to use VEE to communicate to a EchoTherm Programmable Digital Hot Plate Model HS40 via RS-232. This is not a IEEE-488 compliant device and therefore doesn't respond to SCPI commands like "*IDN?". It uses only simple single-lettered ASCII commands like "a", "B" or "c". I have successfully communicated with the hot plate using a USB-RS232 cable (COM4) and Windows Hyperterminal program with the following settings: 2400 Bauds, 8 Data Bits, 1 Stop Bit and No Parity.

My question is how do I get VEE to communicate with this hot plate via RS232?  :?: I have tried using Instrument manager with I/O Libraries but wasn't successful. The Agilent I/O library couldn't even detect the hot plate.

Thanks for your help!
