Hello all.
I need a hand with mode command.
Using MS-DOS 5.0 on an HP 8000 Elite SFF. Have a Raven 2406 parallel printer attached to COM1 via a 6 foot long Black Box PIO45A DB9 to Centronics serial to parallel converter. COM1 is set in the autoexec.bat file to "mode com1:48,n,8,1,p" and the converter (DIP switches) to flow control=hardware, no parity, 8 bits, stop bit=1, data rate=4800. The printer works just fine for days on end, even after daily shutdowns and restarts, but then nothing is printed. No error messages, it just doesn't print. Nothing is changed in the hardware or software. Tried reissuing the same mode command just before printing to no avail. Several restarts later it works again for days, then nothing. Changing COM1 and adapter settings is not an option, as 7bits (1 or 2 stop bits) results in lost print content.
My question: Is there a way to get MS-DOS 5.0 to report the current COM1 setting (without issuing a command to change it)?
Thanks for any help in solving this mystery.
