I've seen some advertised here and there in the > past, but now that I'm looking for one I can't find one, go figure. I know we are talking about isdn adapters..but.. I've a hayes optima 288fm.. all hayes internal and pcmicia modems (and their communication adapters/serial cards) have this special UART chip tat looks like a 16550 but works 2x the speed, so giving 230kps I wonder if the Hayes ESP adater comes in PCMCIA ??
