Once again, nothing in DOS limits > how high you set the UART speed No, he's right. The MODE command under MS-DOS 6.0 as well as Win98 is arbitrarily limited to 19200bps. Doesn't mean that other programs can't set a higher speed themselves, but MODE cannot. However under Windows 7 32-bit, the MODE command doesn't appear to have any limits. (I can set eg. MODE COM3: baud=666666 and it will accept that, although this is not a "real" serial port) ------------------------------------------------------------------------------ Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
