Cermetek CH1786A 2400 bps Modem Module

Back in the day we didn’t have IoT or the Internet! We have to dial in to another computer system via modem. These embedded modem modules have been sitting in a parts drawer for years! I haven’t had a land-line in a long time or I’d find a use for them. These are a somewhat rare item these days. Especially at this price! See description below for complete product details.
