[comp.sys.ibm.pc] need help with Turbo C & serial ports!

hi folks!  thanks again for all the help with the kermit->procomm problem.

my latest program must do serial input & output on a PC...  i'm using
Turbo C.  it has the handy device 'stdaux'.  my program hangs up
immediately when i make the first IO call to stdaux -- DOS error
"error writing to COM1: abort, retry, get a new os ?"  -- you know
the error message i mean, hopefully.

my solution is a bit nonstandard and i'd like to find out why DOS
doesn't like my attempts to read & write the serial port.  my program
works fine when i run it under DRI Concurrent DOS (a real OS, by the way!).

so what is DOS complaining about???  (we know what i'm complaining about!)

thanks in "advance, retry, ignore"...
