NOTE
When conducting a Terminal Session, always select VT100 mode prior to making the craft connection.
The terminal interface operates at data rates from
1.2kbps to 19.2 kbps. The asynchronous data format is fixed at 8 data bits, no parity, and 1 stop bit. The supported terminal type is VT100 or compatible.
NOTE
If using a personal computer (PC) with terminal emulation capability, disable all power saving programs. Otherwise, communication between the PC and the IDSL
