TSTHOST is a software written for TNC2 and clones with HOST mode EPROM type TF8, TF23, TF24 etc. It is possible to use the software with other TNCs set in KISS mode A TNC in KISS mode requires a serial driver (like TFPCX/TFPCR but don't forget to set the TNC in KISS mode BEFORE running TSTHost A TNC in WA8DED Host mode requires a serial driver like COMBIOS, MBBIOS etc. The GKJBIOS driver is an MBBIOS compatible driver optimised for TSTHost, that detects the special 16550A UART. For the driver configuration, run GKBIOCFG.EXE and follow the instructions displayed on the screen TSTHOST offers from 2 to 8 independent communication channels where every channel has a 300 lines receive buffer, circular keyboard buffer to recall the ten previous commands, automatic text justification, up to 8 simultaneous YAPP (with resume and yappC options) or ASCII file transfers, up to 8 PMS channels with RLI-type forward with a master BBS. All received data can be saved in a disk file. Every session may have a different callsign There is a separated window for monitoring, and it is possible to capture in a file all the traffic displayed in that window The text entered from the keyboard is recognised as commands to run for every COMMAND mode session, while in CONVERSATION mode is sent to the connected station. For this reason it is not possible to switch in conversation mode if the session is not connected. The exception is the Monitor window, where all keyboard data is transmitted as Unproto packets For every session there is a receive buffer, useful to review all the received data. By receiving data from a channel not actually selected, the related callsign in the status line will blink. All unconnected channels are set by default to PMS sessions. So, when an user connects your station, he goes into the personal mailbox system, but if YOU connect a user the channel is set for a normal conversation mode. Naturally, you have a specific command to switch a PMS session into conversation mode and vice-versa. During a PMS session, the user can read and write messages, view the users directory, up or download programs
