I tell you what the problem is: those funny lights are not only nice but
also they have certain functions. Just yesterday I bought a secondhand
external modem (28.8). First it didn't want to dial out than it only
pretended to hang up. Only due to the lights of the front panel I could
corrected these Carrier Detect failures and won't have to pay my entire
fortune to my telco & ISP.
That's the reason why your internal modems are so cheap. Or have you
ever seen internal modems in a professional IT environment ? ;-)
As for as trouble at setup: you can search for a free IRQ for each and
every internal serial device, or you can get an intelligent serial line
multiplexor board with 4-8 ports that uses _one_ IRQ with all of your
external serial devices. Such things work very efficiently in old
survival PCs.
