Multiple Monolithic Serial Drivers

OSR_Community_User · May 10, 2007, 9:39am

is it possible to have multiple (monolithic) serial drivers installed and running on one machine? i’m assuming no because …

i can’t get seem to get one installed without disabling the other
the ISR would have to be different for the different ports/interrupts

any assistance is much appreciated…

Yes, it is possible ot have a different serial drivers on the machine at the same time. Each driver controls its own hardware though. You cannot have 2 drivers controlling the same device instance (like COM1), rather one controls COM1, another controls COM2.

Doron,

thanks for the reply. with renewed optimism i attacked the INF file again and the system now appears to have the desired result - my driver on COM1, standard ms driver on other com ports. however, i added a custom IOCTL in the driver so an application can confirm that it is installed and it seems to respond on all of the com ports. when i remove my driver the new IOCTL returns an error as expected. also, the driver install doesn’t really kick in until after a reboot, but the device manager doesn’t request one?

for the time being i’m installing via the device manager, though i’d like to do it programmatically eventually, which brings me to another question - how can i make UpdateDriverForPlugAndPlayDevices() update a driver for an existing port rather than adding a new one?

i’ve attached my INF file (slimmed down from msports.inf) for reference in case the problem lies there - thanks again!

Don’t name your service “serial” (remember the name of the service does
not necessarily map 1:1 with the name of the binary). Change this

AddService = Serial, 0x00000002, Serial_Service_Inst,
Serial_EventLog_Inst

To
AddService = AmtSerial, 0x00000002, Serial_Service_Inst,
Serial_EventLog_Inst
