I have a fairly new 2400 Smart One modem that's behaving strangely recently. Since I have two serial ports, the modem is set for com3, and it has been working fine for two months. Then yesterday it refused to connect though it dialed OK (I am sure it's not the mainframe because I tried several different hosts with the same results). Then I changed the switches to make it use com4, which worked fine until this morning whne it refused to connect again. I immediately changed the dip switches to come back to com3, with the expected success. This is surely not what one likes a modem to do. I am thinking of sending it back to the vendor. But I would like to hear from you about this behavior. Thank you in advance. Jining Han

Thank all those who replied to my question about the behavior of my modem. All suggested that the problem is probably caused by the fact that com1/com3 and com2/com4 share the same interrupts. Indeed I might have co-incidentally switched the port for my mouse each time I switched the modem port. Anyway, things are pretty normal right now and hope that it stays so. Many thanks again.
