Modem/RS232 menu

The RS232 interface of the MSK 33 can be configured in the most important points in this menu.

Return to the ‚SETTING menu.‘

Setting baud rate

rate < >

The field lights up yellow, as soon as the softkey is pressed. Afterwards, the inter- face speed from 2400 to 115200 baud (each 8 bits / no parity /no stop bit) can be set with the aid of the cursor buttons, „<„ and „>.„ This setting is only based on the interface communication between the modem and the MSK 33 and has no influ- ence on the transmission characteristic data of the modem.

Setting local echo

echo off

Normally, all characters received by the modem are sent back by the MSK 33. This means, that a character entered in on the terminal (PC keyboard) is not immedi- ately displayed on the screen, but rather sent via the near modem (on the PC) to the farther modem (on the MSK 33). Here, the character is analysed and sent back (echo function).

If the local echo on the terminal is activated, the character appears twice and one of the both echoes must be terminated.

Setting hardware handshake

r/cts off

By pressing the button, R/CTS, the hardware-handshake can be activated or deac- tivated. If the handshake operation is deactivated, it is not possible for the MSK 33 to recognise, when a connected PC or modem has taken over the operation. In this case, the MSK 33 first answer after entry of a RETURN on the terminal pro- gramme.

If the handshake is activated, this occurs automatically, as soon as the terminal programme has been called up or the modem has been successfully called. If the MSK 33 is switched off during this procedure, it will switch on by itself or switch off after exiting the terminal programme or loss of the carrier on the modem.

Init (Initialisation string) for the MSK 33 modem

init < >

Here, the currently valid initialisation string for the MSK 33 modem can be read. With the aid of the initialisation string, a connection to the MSK 33 modem is estab- lished after switching on the MSK 33. With this, a change of the basic setting in the modem is carried out, for example the setting of a common baud rate. A change of the initialisation string can occur after pressing the INIT button. Hereby, it is possi- ble to select the character with the cursor buttons, or to select the position which is to be edited. The character string is sent to the first space after deactivating the INIT button.
