I see two potential "issues" with the information in your message.

First, the Kenwood TS-950 series radios use serial port parameters of 4800-8-N-2. Notice it uses two stop bits instead of the "normal" one stop bit.

The second issue is how much flexibility you have with the serial ports. For starters, the standard serial port addresses are as follows:

COM1: 3F8 irq 4
COM2: 2F8 irq 3
COM3: 3E8 irq 4
COM4: 2E8 irq 3

The serial card book is telling you that using 3E8 and 2E8 will enable COM3 and COM4. This is a "safer bet" on their part because some older computers had one hardware port assigned to COM1 and an internal modem card assigned to COM2 (or it could have two hardware COM ports).

The CT manual says it expects the standard serial port addresses and IRQ's as follows:

COM1: 3F8 irq 4
COM2: 2F8 irq 3
COM3: 3E8 irq 2
COM4: 2E8 irq 5

Notice COM3 & 4 are changed to IRQ2 and 3 respectively. Your new serial card probably has jumpers to allow you to reconfigure its addresses and IRQ's.

When you setup COMTSR1, you can assign Port, Baud rate, IRQ, Data format, Flow control, Software Int, and Port address. Make sure you use the correct ADDRESS and IRQ for your circumstance and 8N2 for the Data format.

Hopefully these tips will give you some insight to resolve the problem you have. I used CT and a TS-950 for many years and it worked great.

I did post this Query on CT Reflector but thought
I'd cover my bases in case someone here knows answer

I have a Celeron machine running DOS/WIN98SE
I am trying to get CT Ver 10.003 set up for a ham friend

Problem is it only has 1 COM port on Mother Board
and I need 2, 1 for Telnet Packet ands 1 for Radio Control
( Using Printer Port to key rig for CW - that works fine )

I managed to find a NEW 2 COM Port ( 2 DB-9s connectors)
PCI board which I installed and the floppy disk that came with it
had drivers for DOS and also WIN98

I did check the company's web site for any new drivers
and the DOS and WIN98 drivers were the same as on the diskette

Machine is set to boot into Straight DOS without
loading any Windows Driver
( set GUI=0 in System.ini file )

That works fine, it boots into DOS on turn on

I installed the card and DOS driver and I am able to
do a port test with a DOS Utility and both COM ports
checkout fine.

In the CT Directory I load
COMTSR1 ( For my Telnet Packet input and that works fine )

I am trying to do radio control for a
Kenwood TS-950 on one of the new ports on the
Plug in serial card

I typed

COMTSRX -A2E8 -B4800
( Where X = 2, 3 and 4 com ports.....to no avail)

Any ideas what I am doing wrong

The Blue confirmation Window always comes up and verifies that
I did in fact get the  desired COM port and the port address

( The Serial card booklet instructed me that port addresses
are 2E8 and 3E8

( N81 for other defaults as usual )

I also went into WIN 98 and loaded those drivers just to be sure
WIN98 sees the ports and all is well there but I know not
to run CT for DOS in WIN98

I do NOT want to run CTWIN if I can help it as have
had too many problems in the past with Video chipsets etc
not working correct with CTWIN )

Ant DOS gurus out there with some other solutions ?
