  COMSW program, to show COM ports that are active in your computer.


  Enter   COMSW

  at any prompt.  COMSW is Freeware.


  Example output:

  [This shows 3 active COM ports.  They have "UART" chips, which are
  the standard chips for a serial port in an IBM-type computer.
  Important:  If the COM port can use high speeds in Windows
  the list will say YES.]

ComSw V0.1a (c)1992 T N Channon
Usage: comsw {/<flags}
 Flags are /fbwpsedrlqmh? but most take numeric args. There may be none or more
 sets of flags separated by spaces. Invoked with no args just displays status.
  /<port> where port is 1..4 eg. /3 is flags for COM3
  f0|1 where 0 is disable and 1 is enable FIFO if present
  b<baud> where baud is a number eg. b38400
  w5|6|7|8 number of databits in Word
  pE|O|N Even, Odd or No Parity
  s1|2 One or two stop bits.  L0|1 sets Loopback state.
  e0|1 where 0 is disable and 1 is disable IRQ for port
  d0|1 sets DTR state.  r0|1 sets RTS state
  q    Quiet mode, no display.
  m    monitor port handshake lines
  h|?  display this text!
 All flags are case insensitive. Errorlevel returned.
 Flags may be in any order and ports may be in any order.
 Example: comsw /1b9600w8pns1e1 /3e0
