Ascend - Modem Init Strings


Disclaimer: These strings are suggestions only. There are so many factors [PC or Mac, type of UART, OS, Dialer, type of phone service, etc.] that these can only be looked at as guidelines. Some of these strings have come from the field and have not been tested by Ascend. If there's only one entry, that should be for maximum speed with Error Correction and Data Compression (EC/DC)
