MSWIN Serial Port Driver

We want to use a serial port in a "real time" application under Win3.1x and Win95.
We need advice to use COM.DRV or another driver which will allow us:
a) to work at 115kbps or 230kbps.
b) to get, together with a character received, the status of several control signals (ie CD, CTS etc...) DURING this character reception.
without a polling loop.

Thanks & regards

Pacific Commware had a series of parallel port hardware including drivers for Win95 which allow speeds up to 921kbps. They provide Win95 driver that let your application set the baudrate to more than just 115.2kbps so this might be a solution for your a) question.
Regarding b): I think you have two options:
1. You could write your own serial driver. Not pretty, but not that hard to do if you have MSDN Library including the DDK. Microsofts Device Driver Kit includes the sample for the vcd.vxd and also the serial.vxd port driver. Using these you could do it or
2. Bypass the device driver by inserting your own VXD only for this purpose (might be easier because you don't need to watch out for all the problems related to a full-featured serial driver).

Hope this helps,
Claus

Yes I could, I did write a serial port driver before for one client, so I could change it to support your needs. But this also poses one small problem: I can't deliver competitors with the same code (would be unprofessional, would'nt it?), so I need to know some more details about your application.
From what you wrote in your question I currently see no conflict.
Please contact me via email: ClausChristensen@msn.com.
