PC Rmt WRmt: Connecting Asynchronously at Different Speeds

• Microsoft Mail Remote for MS-DOS, versions 2.1, 3.0, and 3.2
• Microsoft Mail Remote for Windows, version 3.2

SYMPTOMS

In versions 2.1, 3.0, and 3.2 of Microsoft Mail Remote for MS-DOS and version 3.2 of Microsoft Mail Remote for Windows, you should use identical modems on each end of a communication session. However, when you use the Hayes V-Series modems with the VSERIES.SCR file, it is possible for the modems to connect at a different speed. For example, the calling modem might connect at 9600 baud, when the called modem might connect at 2400 baud. This results in a time-out failure when mail is sent from the called modem (2400 baud) to the calling modem (9600 baud).

CAUSE

Versions 3.0 and later of Mail Remote includes two V-Series scripts. One is for the V4.2 family (V42SERIE.SCR) and the other is for the V-Series Smartmodems (VSERIES.SCR). Only the V42SERIE.SCR can work with different connection changes such as 1200 and 2400 baud. However, only the VSERIES.SCR can call out at high speed (9600 baud and higher).

V42SERIE.SCR works with 1200, 2400, 9600, and 19200 baud in Call-OUT and Call-IN connections.

VSERIES.SCR works with 1200, 2400, 9600, and 19200 baud in Call-IN connections, but only works with 9600 and 19200 baud in Call-OUT connections.
