SIM Bank(Box)串口号与槽位号对应关系

Question

我需要映射SIM卡的串口号和插槽。 我的SIM卡有256个插槽（8个端口，32个插槽），盒子的每个端口连接8个串口。 如何获取 8 个 COM 端口映射的银行端口号？

import serial.tools.list_ports
import logging

def execute_command(modem, command, wait_time=2):
    try:
        modem.write(f"{command}\r".encode())
        time.sleep(wait_time)
        return modem.readlines()
    except serial.SerialException as e: 
        print(f"Error executing command {command} in {modem.port}: {str(e)}")
        return []

try:
    modem = serial.Serial("COM" + str(real_port), 115200, timeout=1)
    for i in range(132, 164):
        sub_modem.append(serial.Serial("COM" + str(i), 115200, timeout=1))

    print(f"########## Real Port: {real_port} ##########")

    for index, modem_cop in enumerate(sub_modem):
        for port in range(1, 9):
            formatted_string = "AT+SWIT{:02d}-{:04d}".format(port, 1)
            response = execute_command(modem, formatted_string)

            try:
                operator = ''.join([line.decode('utf-8', errors='ignore') for line in response])
            except UnicodeDecodeError as e:
                print(f"Decoding error: {e}")
                continue
                
            if str("SWITCH OK") in operator:
                try:
                    res_cop = execute_command(modem_cop, "AT+COPS=?")
                    try:
                        oper_cop = ''.join([line.decode('utf-8', errors='ignore').strip() for line in res_cop])
                  
                    except UnicodeDecodeError as e:
                        print(f"Decoding error: {e}")
                        continue

               
                except Exception as e:
                    print(e)

    for index in enumerate(sub_modem):
        sub_modem[index].close()
    modem.close()

    print(f"########## Real Port: {real_port} ##########")
    logging.info(f"########## Real Port: {real_port} ##########")
except Exception as e:
    print(f"Error: {e}")

您可以使用 pyserial 库编写 Python 脚本来查询每个 COM 端口并发送识别 SIM 卡上相应端口和插槽的特定命令。
