- I have a Epson 14.4 PC card modem (PCMCIA). Iam not sure if it is CID
- capable (posibly not). But It does accept CID command, that is, if
- you type AT#CID=1it returns OK. Then when someone dials in it picks
- up the call after the second ring. I don't know if I can make it CID
- capable. Do I need change the modem. Can usual CID box export data
- to computer?
