| 2784.4 | 450ST serial ports | NUBOAT::HEBERT | Captain Bligh | Wed Apr 23 1997 15:05 | 15 |
| My DECpc has two serial ports. One (COM2) is occupied by my internal
modem board.
I need to connect to the other serial port, to interface with a new
amateur radio rig. The radio's port characteristics are 9600 baud, 2 stop
bits, and so forth. So I went into Control Panel, Ports, and set COM1 to
the required parameters. I connected the correct cable (it came with the
radio) to the external comm port connector on the back of the PC, but I
can't seem to make anything work.
Do I have to disable the modem somehow?
Thanks,

| Usually anything faster than a pigeon takes 1 stop bit, not 2
(but that probably isn't the problem). Is there a way you can
verify the COM1 port is working in a simpler environment?
(say, hook up a serial mouse, and/or a serial mouse having booted
with just a DOS diskette and mouse driver).

| 2784.6 | Not so intuitive: use the printer port | NUBOAT::HEBERT | Captain Bligh | Thu Apr 24 1997 09:01 | 26 |
| Well, I answered my own question last night. For the possible benefit of
other, here's the fix - and explanation.
The back of the DECpc 450ST has (among others) three connectors:
9-pin D with two arrows drawn over it; manual describes it as
"Serial Comm Port"
9-pin D with a printer drawn over it; manual describes it as
"Serial Printer Port"
25-pin D Parallel Printer Port
I've been trying to make the "Serial Comm Port" talk to my radio. Last
night out of desperation I connected to the Serial Printer Port and my
radio software took off. (9600 baud, 2 stop bits, no parity was
previously set up for COM1 per the radio specs.)
I was able to program my new ham rig in no time at all. Much better than
pressing several microphone buttons in specific sequences, holding this
one for x seconds, now power down, now power up... Plus, I now have a
file that can be used to restore the setup if I fumblefinger and wipe it
out in the radio.

From what I remember, com1 was occupied by the mouse.
If you can run MSD, check out the comm port status.

| Thanks for replying. The 450ST has a separate mouse port - is that a
PS2-type?
Anyway, I accomplished what I needed to do. Now if only I could use my
320P notebook for this purpose, that would be a plus. Unfortunately, the
320P uses the serial port for the serial mouse, and the software that I
have to program the radio makes heavy use of mouse input. I never did
learn how do to windows things without a mouse, although I think you can.
