- Hello.
-
- Yesterday I installed a "RTA-451 2 serial/parallel" card on my PC. I already
- got one parallel and two serial ports on the machine, so I configurated the
- serial ports to COM3: and COM4: and the parallel port to LPT2:
-
- Before I installed the card I ran the Microsoft Diagnostic Version 2.00
- program to check the status on the COM1:, COM2: and LPT1: port. Based on the
- output from the program I configurated the RTA-451 card as follow:
-
- ACE1 configurated as COM3: at address 3E8 with IRQ4.
- ACE2 cinfigurated as COM4: at address 2E8 with IRQ3.
- LPT configurated as LPT2: at address 278 with IRQ5.
-
- After the installation I ran the diagnostic program to check the status again.
- The LPT2: port was recognized by the program, but COM3: and COM4: was still
- N/A.
-
- Have I done anything wrong since the diag. program won't accept the extra COM
- ports? Everything on the machine seems to work just fine. The mouse work
- (connected to COM1:) and the external modem on COM2: work just fine.
-
- COM1: and COM3: will both have IRQ4 and COM2: and COM4: will both have
- IRQ3, while LPT1: have IRQ7. Will this work?
-
- If I get COM3: and COM4: to work from DOS, will they be recognized by Windows
- 3.1? Anything I have to do to make them work from Windows?
-
- Please e-mail me, I do not subscribe to this group. Thanx
