Description

Com_SendMode() controls the Write Timeout processing characteristics of the physical device driver.

Two modes can be specified with <nMode> using #define constants from XBTCOMP.CH:

- WRITE_TIMEOUT

A write request will not return later than the period of time specified by <nTimeout> elapses, even if not all of the data could be send.

<nTimeOut> - timeout value in .01 second units (0 = .01 seconds!)

- INFINITE_WRITE_TIMEOUT

A write request is not completed until all of the data has been sent. <nTimeOut> will be ignored.

Default mode set when calling Com_Open() the first time for a COM port: WRITE_TIMEOUT with a timout value of 100.
