Serial port recommendations?

Serial port recommendations?

[Bob Nielsen]

I just built a new computer (1 GHz Celeron) for the shack.  It has 2
onboard serial ports and I was wondering what would be the best way to
add additional ports.  I figure I need 2-3 for packet, one for rig
control, one for RTTY/PSK31 PTT and one for CW keying (5-6 total if I
don't switch connectors).  The motherboard has several PCI slots and
one ISA, as well as two USB connectors.  I have one old 2-port ISA
board and I've seen USB-to-serial adapters, but figure a 4-port serial
adapter might be best.  I haven't seen any of these recently, however. 
The software I will be using is kernel AX.25 + DX Spider + Xastir
(packet) and TLF (contesting and general HF use), plus something for
RTTY and PSK31, (I haven't decided exactly what yet.)

Any suggestions on the best way to get additional serial ports?

I've had good luck with both PCI and ISA cards from Dolphin.

I bought two of the cards, took the UART chips out of one, and
placed them in the other for a 4 port card.

We've been using RocketPort cards in a lot of machines, mostly
8-port cards with a few 16-port cards lately.  We've been more than
pleased with them.  You can get them in ISA or PCI versions.  Not
sure if they fit your budget, but they work awfully well.  They have
drivers for Windows and Linux at least, perhaps others.

Thanks for the tip.  They appear to sell through several sources who
put their own part number on the cards (there is a direct special
shown, but the offer expired last year!).  The cross-reference doesn't
show the card I was intererested, but based on what IS shown, I think I
found it (a 4-port 16550-based PCI card) at JDR for a fairly good
price ($66).
