 If your DOS terminal program of choice has trouble dialing long dial strings (e.g. accommodating long DNS hostnames or IPv6 addresses), try using the saved number storage feature to resolve that limitation. After enter the following command, dialing "S0" as a "phone number" would actually connect to "telnet:vert.synchro.net:23". If your DOS terminal program of choice has trouble dialing long dial strings (e.g. accommodating long DNS hostnames or IPv6 addresses), try using the saved number storage feature to resolve that limitation.

 +Another option for dialing longer dial strings is to specify "aliases" in the ''[alias]'' section of your ''svdm.ini'' file. Any combination of printable ASCII characters may be used for a dial string alias, except for the colon ('':'') and equals (''='') characters.
