FAQ

I get errors when running remote over RDP/Terminal Services or RS232 over TCP/IP?: The default timeouts set in the driver are suitable for cards directly connected to a local computer. For running over TCP/IP timeouts will have to be increased. Try starting with 100 ms, and increasing by 100ms until the communication is stable.
How do I use virtual serial ports in my VMware/Terminal Services/Virtual PC sessions?
How do I use an USB-port or a Ethernet to RS232 port?: Upgrade to the OLTOM Card Driver DLL and/or the latest SMCP program. Please contact support if you have an earlier version and need to update.
What causes “DLL not found” exceptions when trying to run my program?: Copy the oltom-card-driver.dll into the same directory as your application or add the directory containing oltom-card-driver.dll (usually C:\Program Files\OLTOM\oltom-card-driver) to the path.
Which priority do the DLL threads run with?: On Windows the default thread priority is THREAD_PRIORITY_TIME_CRITICAL.; On Linux the default thread priority is realtime scheduling SCHED_FIFO, lowest priority within SCHED_FIFO.
