I'm building a VB app that communicates with a noise station though a modem line. So far i've been able to establish a connection with the remote modem. I send the command MSComm1.Output = "ATDT96477599" & vbCrLf to establish the communication and get "CONNECT 300" as a response. Then I need to login the noise station, so I send my password like this MSComm1.Output = "password" & vbCrLf. I get a stange response that consist on an unreadable string. Then after, if I try to send another command I get the response "NO CARRIER". I don't know what it means. Any help would be much appreciated.
