我买了一台中兴MF190 USB调制解调器并开始利用它。
到目前为止,我已设法使用 TurboPowers 的免费 AsyncPro 组件以编程方式将短信发送到另一个移动设备。
我想知道是否有办法检索所有已安装调制解调器的列表及其连接的串行COM端口(希望具有其他有价值的功能)。
提前致谢。

要列出已安装的调制解调器,您可以使用Win32_POTSModem
WMI类
检查此示例代码。
{$APPTYPE CONSOLE}
uses
SysUtils,
ActiveX,
ComObj,
Variants;
procedure GetWin32_POTSModemInfo;
const
WbemUser ='';
WbemPassword ='';
WbemComputer ='localhost';
wbemFlagForwardOnly = $00000020;
var
FSWbemLocator : OLEVariant;
FWMIService : OLEVariant;
FWbemObjectSet: OLEVariant;
FWbemObject : OLEVariant;
oEnum : IEnumvariant;
iValue : LongWord;
begin;
FSWbemLocator := CreateOleObject('WbemScripting.SWbemLocator');
FWMIService := FSWbemLocator.ConnectServer(WbemComputer, 'root\CIMV2', WbemUser, WbemPassword);
FWbemObjectSet:= FWMIService.ExecQuery('SELECT * FROM Win32_POTSModem','WQL',wbemFlagForwardOnly);
oEnum := IUnknown(FWbemObjectSet._NewEnum) as IEnumVariant;
while oEnum.Next(1, FWbemObject, iValue) = 0 do
begin
Writeln(Format('AttachedTo %s',[String(FWbemObject.AttachedTo)]));// String
Writeln(Format('DeviceID %s',[String(FWbemObject.DeviceID)]));// String
Writeln(Format('Model %s',[String(FWbemObject.Model)]));// String
Writeln(Format('Name %s',[String(FWbemObject.Name)]));// String
Writeln(Format('PortSubClass %s',[String(FWbemObject.PortSubClass)]));// String
FWbemObject:=Unassigned;
end;
end;
begin
try
CoInitialize(nil);
try
GetWin32_POTSModemInfo;
finally
CoUninitialize;
end;
except
on E:EOleException do
Writeln(Format('EOleException %s %x', [E.Message,E.ErrorCode]));
on E:Exception do
Writeln(E.Classname, ':', E.Message);
end;
Writeln('Press Enter to exit');
Readln;
end.
