Serial/Direct and Serial/Modem → Serial/Modem and Serial/Direct Overview
| Context |
This article describes a function or feature of the software ZOC Terminal. The feature or element of the software described here is 'Serial/Modem and Serial/Direct Overview'. ZOC Terminal is a professional terminal emulator that is well known for its extensive features, security, user friendlyness, wide range of emulations and quality of emulation implementation. ZOC Terminal is a common choice to replace other terminal emulators like Putty, Kitty, Termius, Secure-CRT, Attachmate Extra!and others.
This section applies to two similar connection types: Serial/Modem and Serial/Direct
The purpose of Serial/Direct is to connect to gear which is hooked directly to the serial port of your machine, e.g. routers, flash programming devices and such.
The Serial/Modem method should be used to dial out to a remote location using a modem which is attached to the serial port and where the modem is controlled through means of AT-commands (e.g. ATDT <number> to dial).
The two are similar in that they work through serial ports and have almost the same
options, but there are two basic differences between Serial/Modem and Serial/Direct:
1) Serial/Modem will internally issue AT commands to the attached port in order
to configure the modem it and to let it make the connection. Serial/Direct does not
send any commands or text strings by itself.
2) Serial/Modem will operate under the assumption that 'connection' refers to a connection
to a remote location which the modem has made (not connecting to the serial port talking
to the modem itself). With Serial/Direct however, 'connection' means opening the serial
port in order to exchange data with the attached device itself.
If you have preconfigured modems (or modem-like devices like cellular phones) attached to your computer, it will probably be easier to use them in ZOC as Windows-Modems rather than using Serial/Modem, especially if you want to use these to make connections to remote computers (e.g. using a cellular phone to dial into an office computer) rather than sending commands to them directly (e.g. in order to access special features of the cellular phone itself).
For details about how to connect to a remote host via ZOC's Serial/Modem and/or
how to use Serial/Direct to talk to devices which are attached directly to a serial
port, please follow the instructions in Quick Start Guides
