Gary/Mobile List- This sounds a lot like what happened when I tride to use a Zoom 56K modem Model 3000 (this is the follow on to the 2975 .. which works as a 16550A with appropriate reset entry in the pccard.conf). The Model 3000 is recognized as a UART 16450 and then when you use ppp in term mode, it locks the machine solid (you cannot even break into the debugger) both on a 3.3-RELEASE--his notebook-- and my 4.1-S from earlier this month. Unfortunately, I no longer have the card or access to PAO machine to see if this made any difference. As a side note, the Model 2975 did _not_ need the reset under PAO ... only under main FreeBSD .. is there some magic in the PAO sio code that code save our butts here? The other weird thing about this modem is that the Manufacturers ID was completely ignored (generated an error) by pccard[dc] and the model name had to be matched in the pccard.conf entry. #Zoom/PC Card 56K (Model 3000) card "V90&K56Flex PCMCIA FAX MODEM" "" config 0x22 "sio" ? This card was bought by my boss because it looked much like the Model 2975 that worked up until the last big thunderstorm :( He was able to return the card and we mail-ordered a Model 2975. The only fear is that this card will eventually replace the 2975 on the market. The box says on it that it has an onboard DSP, but then goes on to say that it works for Windows 9x, NT, 2000. I fear that we may be seeing more and more questions about this type of modem.
