PySerial 最小 RFC2217 示例：将从串口接收的数据复制到 stdout

另请查看本地串口的相同示例：PySerial 最小示例：将从串口接收的数据复制到 stdout

此示例连接到 10.1.2.3 端口 1234 上的 RFC2217 远程串口。它不向串口发送数据，只将从串口接收的数据复制到 stdout。

pyserial_rfc2217_copy.py

#!/usr/bin/env python3
import serial
with serial.serial_for_url("rfc2217://10.1.2.3:1234", baudrate=115200) as ser:
    try:
        while True:
            response = ser.read()
            if response:
                print(response.decode("iso-8859-1"), end="")
    finally:
        ser.close()

#!/usr/bin/env python3
import serial
with serial.serial_for_url("rfc2217://10.1.2.3:1234", baudrate=115200) as ser:
    try:
        while True:
            response = ser.read()
            if response:
                print(response.decode("iso-8859-1"), end="")
    finally:
        ser.close()

pyserial_rfc2217_copy.py

#!/usr/bin/env python3
import serial
with serial.serial_for_url("rfc2217://10.1.2.3:1234", baudrate=115200) as ser:
    try:
        while True:
            response = ser.read()
            if response:
                print(response.decode("iso-8859-1"), end="")
    finally:
        ser.close()

#!/usr/bin/env python3
import serial
with serial.serial_for_url("rfc2217://10.1.2.3:1234", baudrate=115200) as ser:
    try:
        while True:
            response = ser.read()
            if response:
                print(response.decode("iso-8859-1"), end="")
    finally:
        ser.close()

通过使用 iso-8859-1 解码，我们确保即使二进制字节也以某种方式解码，不会导致异常。
